The IC includes four output buffer amplifiers and input logic for an easy-to-use, two- or three-wire serial interface. In a system with several MAX500s, only one serial data line is required to load all the DACs by cas-cading them. The MAX500 contains double-buffered logic and a 10-bit shift register that allows all four DACs to be updated simultaneously using one control signal.There are three reference inputs so the range of two of the DACs can be independently set while the other two DACs track each other.The MAX500 achieves 8-bit performance over the full operating temperature range without external trimming.________________________ApplicationsMinimum Component Count Analog Systems Digital Offset/Gain Adjustment Industrial Process Control Arbitrary Function Generators Automatic Test Equipment____________________________Featureso Buffered Voltage Outputs o Double-Buffered Digital Inputso Microprocessor and TTL/CMOS Compatible o Requires No External Adjustmentso Two- or Three-Wire Cascadable Serial Interface o 16-Pin DIP/SO Package and 20-Pin LCC o Operates from Single or Dual Supplies______________Ordering InformationMAX500CMOS, Quad, Serial-Interface8-Bit DAC________________________________________________________________Maxim Integrated Products1_________________Pin Configurations________________Functional Diagram19-1016; Rev 2; 2/96*Contact factory for dice specifications.M A X 500CMOS, Quad, Serial-Interface 8-Bit DAC 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual Supplies(V= +11.4V to +16.5V, V = -5V ±10%, AGND = DGND = 0V, V = +2V to (V - 4V), T = T to T , unless otherwise noted.)Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The DACs are “inverted”R-2R ladder networks which convert 8 digital bits into equivalent analog output voltages in proportion to the applied reference voltage(s). Two DACs in the MAX500have a separate reference input while the other two DACs share one reference input. A simplified circuit diagram of one of the four DACs is provided in Figure 1.V REF InputThe voltage at the V REF pins (pins 4, 12, and 13) sets the full-scale output of the DAC. The input impedanceof the V REF inputs is code dependent. The lowest value, approximately 11k Ω(5.5k Ωfor V REF A/B), occurs when the input code is 01010101. The maximum value of infinity occurs when the input code is 00000000.Because the input resistance at V REF is code depen-dent, the DAC’s reference sources should have an out-put impedance of no more than 20Ω(no more than 10Ωfor V REF A/B). The input capacitance at V REF is also code dependent and typically varies from 15pF to 35pF (30pF to 70pF for V REF A/B). V OUT A, V OUT B,V OUT C, and V OUT D can be represented by a digitally programmable voltage source as:V OUT = N b x V REF / 256where N b is the numeric value of the DAC’s binary input code.Output Buffer AmplifiersAll voltage outputs are internally buffered by precision unity-gain followers, which slew at greater than 3V/µs.When driving 2k Ωin parallel with 100pF with a full-scale transition (0V to +10V or +10V to 0V), the output settles to ±1/2LSB in less than 4µs. The buffers will also drive 2k Ωin parallel with 500pF to 10V levels without oscilla-tion. Typical dynamic response and settling perfor-mance of the MAX500 is shown in Figures 2 and 3.A simplified circuit diagram of an output buffer is shown in Figure 4. Input common-mode range to AGND is provided by a PMOS input structure. The out-put circuitry incorporates a pull-down circuit to actively drive V OUT to within +15mV of the negative supply (V SS ). The buffer circuitry allows each DAC output toM A X 500sink, as well as source up to 5mA. This is especially important in single-supply applications, where V SS is connected to AGND, so that the zero error is kept at or under 1/2LSB (V REF = +10V). A plot of the Output Sink Current vs. Output Voltage is shown in the Typical Operating Characteristics section.Digital Inputsand Interface LogicThe digital inputs are compatible with both TTL and 5V CMOS logic; however, the power-supply current (I DD )is somewhat dependent on the input logic level. Supply current is specified for TTL input levels (worst case) but is reduced (by about 150µA) when the logic inputs are driven near DGND or 4V above DGND.Do not drive the digital inputs directly from CMOS logic running from a power supply exceeding 5V. When driv-ing SCL through an opto-isolator, use a Schmitt trigger to ensure fast SCL rise and fall times.The MAX500 allows the user to choose between a 3-wire serial interface and a 2-wire serial interface.The choice between the 2-wire and the 3-wire inter-face is set by the LOAD signal. If the LOAD is allowed to float (it has a weak internal pull-up resistor to V DD ),the 2-wire interface is selected. If the LOAD signal is kept to a TTL-logic high level, the 3-wire interface is selected.3-Wire InterfaceThe 3-wire interface uses the classic Serial Data (SDA),Serial Clock (SCL), and LOAD signals that are used in standard shift registers. The data is clocked in on the falling edge of SCL until all 10 bits (8 data bits and 2 address bits) are entered into the shift register.CMOS, Quad, Serial-Interface 8-Bit DAC 6_______________________________________________________________________________________DYNAMIC RESPONSE (V SS = -5V or 0V)2µs/divLDAC 5V/divOUTPUT 5V/divFigure 3.

Then all of the DAC regis-ters can be simultaneously updated using the LDAC (load DAC) signal. When LDAC is low, the input regis-ter’s data is loaded into the DAC registers (see Figure 5for timing diagram). This mode is cascadable by con-necting Serial Output (SRO) to the second chip’s SDA pin. The delay of the SRO pin from SCL does not cause setup/hold time violations, no matter how many MAX500s are cascaded. Restrict the voltage at LDAC and LOAD to +5.5V for a logic high.2-Wire InterfaceThe 2-wire interface uses SDA and SCL only. LOAD must be floating or tied to V DD . Each data frame (8 data bits and 2 address bits) is synchronized by a timing relationship between SDA and SCL (see Figure 6 for the timing diagram). Both SDA and SCL should normal-ly be high when inactive. A falling edge of SDA (while SCL is high) followed by a falling edge of SCL (while SDA is low) is the start condition. This always loads a 0into the first bit of the shift register. The shift register is extended to 11 bits so this “data” will not affect the input register information. The timing now follows the 3-wire interface, except the SDA line is not allowed to change when SCL is high (this prevents the MAX500from retriggering its start condition). After the last data bit is entered, the SDA line should go low (while the SCL line is low), then the SCL line should rise followed by the SDA line rising. This is defined as the stop con-dition, or end of frame.Cascading the 2-wire interface can be done, but the user must be careful of both timing and formatting.Timing must take into account the intrinsic delay of the SRO pin from the internally generated start/stop condi-tions. The t S2value should be increased by n times t D1(where n = number of cascaded MAX500s). The t LDS value should also be increased by n times t D1. No other timing parameters need to be modified. A more serious concern is one of formatting. Generally, since each frame has a start/stop condition, each chip that has data cascaded through it will accept that data as if it were its own data. Therefore, to circumvent this limita-tion, the user should not generate a stop bit until all DACs have been loaded. For example, if there are three MAX500s cascaded in the 2-wire mode, the data transfer should begin with a start condition, followed by 10 data bits, a zero bit, 10 data bits, a zero bit, 10 data bits, and then a stop condition. This will prevent each MAX500 from decoding the middle data for itself.The data is entered into the shift register in the follow-ing order:A1 A0 D7 D6 D5 D4 D3 D2 D1 D0(First) (MSB) (Last)where address bits A1 and A0 select which DAC regis-ter receives data from the internal shift register. Table 1lists the channel addresses. D7 (MSB) through D0 is the data byte.Since LDAC is asynchronous with respect to SCL, SDA,and LOAD , care must be taken to assure that incorrect data is not latched through to the DAC registers. If the 3-wire serial interface is used,LDAC can be either tied low permanently or tied to LOAD as long as t LDS is always maintained. However, if the 2-wire interface is used, LDAC should not fall before the stop condition is internally detected. (This is the reason for the t LDS delay of LDAC after the last rising edge of SDA.)CMOS, Quad, Serial-Interface 8-Bit DAC8_______________________________________________________________________________________Notes:H = Logic High 2W = 2-Wire L = Logic Low3W = 3-Wire M = TTL Logic High F = Falling EdgeX = Don’t CareTable 1. DAC AddressingThe SRO output swings from V DD to DGND. Cascading to other MAX500s poses no problem. If SRO is used to drive a TTL-compatible input, use a clamp diode between TTL +5V and V DD and the current-limiting resistor to prevent potential latchup problems with the 5V supply.Table 2 shows the truth table for SDA, SCL, LOAD , and LDAC operation. Figures 5 and 6 show the timing dia-grams for the MAX500.__________Applications InformationPower-Supply and ReferenceOperating RangesThe MAX500 is fully specified to operate with V DD between +12V ±5% and +15V ±10% (+11.4V to +16.5V), and with V SS from 0V to -5.5V. 8-bit perfor-mance is also guaranteed for single-supply operation (V SS = 0V), however, zero-code error is reduced when V SS is -5V (see Output Buffer Amplifiers section).For an adequate DAC and buffer operating range, the V REF voltage must always be at least 4V below V DD .The MAX500 is specified to operate with a reference input range of +2V to V DD - 4V.Ground ManagementDigital or AC transient signals between AGND and DGND will create noise at the analog outputs. It is rec-ommended that AGND and DGND be tied together at the DAC and that this point be tied to the highest quali-ty ground available. If separate ground buses are used,then two clamp diodes (1N914 or equivalent) should be connected between AGND and DGND to keep the twoground buses within one diode drop of each other. To avoid parasitic device turn-on, AGND must not be allowed to be more negative than DGND. DGND should be used as supply ground for bypassing purposes.MAX500CMOS, Quad, Serial-Interface8-Bit DAC_______________________________________________________________________________________9Figure 7. Suggested MAX500 PC Board Layout for Minimizing CrosstalkFigure 9. Bipolar Output CircuitM A X 500Careful PC board ground layout techniques should beused to minimize crosstalk between DAC outputs, the reference input(s), and the digital inputs. This is partic-ularly important if the reference is driven from an AC source. Figure 7 shows suggested PC board layouts for minimizing crosstalk.Unipolar OutputIn unipolar operation, the output voltages and the refer-ence input(s) are the same polarity. The unipolar circuit configuration is shown in Figure 8 for the MAX500. The device can be operated from a single supply with a slight increase in zero error (see Output Buffer Amplifiers section). To avoid parasitic device turn-on,the voltage at V REF must always be positive with respect to AGND. The unipolar code table is given in Table 3.Bipolar OutputEach DAC output may be configured for bipolar opera-tion using the circuit in Figure 9. One op amp and two resistors are required per channel. With R1 = R2:V OUT = V REF (2D A - 1)where D A is a fractional representation of the digital word in Register A.Table 4 shows the digital code versus output voltage for the circuit in Figure 9.AGND can be biased above DGND to provide an arbi-trary nonzero output voltage for a “zero” input code. This is shown in Figure 10. The output voltage at V OUT A is:V OUT A = V BIAS + D A V INwhere D A is a fractional representation of the digital input word. Since AGND is common to all four DACs,all outputs will be offset by V BIAS in the same manner.Since AGND current is a function of the four DAC codes, it should be driven by a low-impedance source.V BIAS must be positive.CMOS, Quad, Serial-Interface 8-Bit DAC 10______________________________________________________________________________________Table 3.

Bipolar Code TableNote:1LSB = (V REF ) (2-8) = +V REF–––256Note:1LSB = (V REF ) (2-8) = +V REF –––256Using an AC ReferenceIn applications where V REF has AC signal components,the MAX500 has multiplying capability within the limits of the V REF input range specifications. Figure 11 shows a technique for applying a sine-wave signal to the refer-ence input, where the AC signal is biased up before being applied to V REF . Output distortion is typically less than 0.1% with input frequencies up to 50kHz, and the typical -3dB frequency is 700kHz. Note that V REF must never be more negative than AGND.Generating V SSThe performance of the MAX500 is specified for both dual and single-supply (V SS = 0V) operation. When the improved performance of dual-supply operation is desired, but only a single supply is available, a -5V V SS supply can be generated using an ICL7660 in one of the circuits of Figure 12.Digital Interface ApplicationsFigures 13 through 16 show examples of interfacing the MAX500 to most popular microprocessors.MAX500CMOS, Quad, Serial-Interface8-Bit DAC______________________________________________________________________________________11Figure 11.

Similar to the XYR 6000 wireless transmitter,the SmartLine Wireless product line is part of theHoneywell OneWireless™ system and is ISA100 -ready.The SmartLine Wireless Temperature transmitterenables customers to obtain data and createinformation from remote and hazardous measurement locations without the need to run wires, where running wire is cost prohibitive and/or the measurement is in a hazardous location. Without wires, transmitters can be installed and operational in minutes, quickly providing information back to your system.The previous generation transmitters primarily were applied to monitoring applications but experienced users know that Honeywell’s wireless products are as reliable, secure, and safe as their wired counterparts. With this knowledge, users are now looking for wireless transmitters for use in specific control applications.Figure 1 — SmartLine Wireless Temperature DITransmitterSmartLine Wireless introduces a step change in performance and most notably, performance suitable for control. SmartLine Wireless performance is improved in these ways:•Fast ½ second publication rate.•Higher radio range coverage.•More powerful 4dBi integral antenna.•Smarter local display with more localdiagnostics and radio signal and qualityindicators.•More input channels and types than earlier.XYR 6000 Wireless Pressure Transmitter Differential Pressure Models 2SmartLine Wireless Temperature retains the following desirable features from the XYR 6000 product offering:•Mesh or non-mesh configuration within each transmitter.•Generic, off-the-shelf lithium ion battery.•Two “D” size batterie s for longer life.•Choice of over-the-air or local provisioning (network security join key).•Over-the-air firmware upgrade capability.•Unique, encrypted provisionng key delivered from the factory.•Remote and integral antenna options.•24 VDC power option.•Publication rates of 1, 5, 10, or 30 seconds, plus new selections of ½ seconds and 1, 15,30, 60 minutes.•Transmitter range (integral antenna) of 1150’ (350 m) under ideal conditions.The STIW400 is a high-performance Temperature transmitter featuring performance over a wide of temperature configurations and applications.The SmartLine family is also fully tested and compliant with Experion® PKS providing the highest level of compatibility assurance and integration capabilities. SmartLine easily meets the most demanding application needs for Temperature measurement applications. SmartLine Wireless FeaturesLocal and over-the-air provisioning capability:All Honeywell wireless devices feature a secure method to join the local wireless network, also known as provisioning. SmartLine Wireless transmitters feature two methods to provision a transmitter onto the network which are eitherby using a handheld device to locally communicate through the IR interface or remotely using the over-the-air function. The over-the-air function is managed by the OneWireless gateway, Wireless Device Manager (WDM). Over-the-air firmware updates:Once joined as a member of your OneWireless network, the WDM can download new transmitter firmware releases to each SmartLine Wireless transmitter over the wireless network. Locating and accessing the transmitter locally is not required thus saving time and keeping your personnel in safe environments.Mesh and non-mesh capability: All SmartLine Wireless transmitters can be configured to operate in either a mesh network or a star (non-mesh) network. The configuration is specific to each wireless transmitter and thus the network can consist of a mixture of meshing and non-meshing devices. Non-meshing is desirable for deterministic communications which is preferred for control. Transmission power setting:To comply with local and regional requirements, SmartLine Wireless transmitters are set at the factory to the maximum transmission power setting allowed for the country of use.Non-proprietary battery:Sourcing lithium thionyl chloride batteries is much simpler since SmartLine Wireless utilizes commercial off-the-shelf batteries. Please see the list of approved battery manufacturers later in this specification. Batteries are housed in an IS-approved battery compartment making battery changes safe and easy. Backward compatibility:SmartLine Wireless transmitters can join existing OneWireless networks and interoperate with existing XYR 6000 wireless transmitters or otherISA100 Wireless compliant transmitters or networks.OneWireless Network FeaturesThe core of the Honeywell wireless solution is the OneWireless Network which consists a gateway, access point(s), and field routers.The Wireless Device Manager (WDM) serves as the gateway function and in this role, manages the communication from the wireless field devices to the process control application. Typically, the WDM connects logically to the process control network (Level 2 or wireless DMZ). As the wireless network manager, the WDM provides easy access to the entire wireless network through a browser-based user interface. The Honeywell WDM can manage devices communicating over theISA100 Wireless protocol and the Wireless HART protocol.The ability to deploy redundant WDMs improves the reliability ensuring no loss of process data which is a requirement for control applications.The Field Device Access Point (FDAP) serves in two roles in the OneWireless network infrastructure, which are: 1) access point, and 2) field router. As an access point, the FDAP directly connects to the WDM via Ethernet LAN cable. More than one access point is permitted and, when more than one is present, it ensures dual path for communications into the WDM from the field devices. As a field router, the FDAP located in the field would communicate to the FDAP acting as an access point. Using the FDAP as a router is more efficient than using field devices as routers since FDAPs are line powered devices whereas field devices are typically battery powered, and the FDAP offers greater range. The meshing capability of FDAPs allows flexibility in the setup of the wireless network to fit the requirements for wireless network performance, in terms of reliable communications, performance, and future growth. The choice of non-meshing network may be desirable for reduced communication latencies with a FDAP serving as a field router.Wireless Specifications*Actual range will vary depending on antennas, cables and site topography.SpecificationsOperating Conditions1 The Ambient Limits shown are for Ordinary Non-Hazardous locations only.

The MAX5481/MAX5482 are 3-terminal voltage-dividers and the MAX5483/MAX5484are 2-terminal variable resistors.The MAX5481–MAX5484 feature an internal, non-volatile, electrically erasable programmable read-only memory (EEPROM) that stores the wiper position for ini-tialization during power-up. The 3-wire SPI-compatible serial interface allows communication at data rates up to 7MHz. A pin-selectable up/down digital interface is also available.The MAX5481–MAX5484 are ideal for applications requiring digitally controlled potentiometers. Two end-to-end resistance values are available (10k Ωand 50k Ω) in a voltage-divider or a variable-resistor configuration (see the Selector G uide ). The nominal resistor temperature coefficient is 35ppm/°C end-to-end, and only 5ppm/°C ratiometric, making these devices ideal for applications requiring low-temperature-coefficient voltage-dividers,such as low-drift, programmable gain-amplifiers.The MAX5481–MAX5484 operate with either a +2.7V to +5.25V single power supply or ±2.5V dual power sup-plies. These devices consume 400µA (max) of supply current when writing data to the nonvolatile memory and 1.0µA (max) of standby supply current. The MAX5481–MAX5484 are available in a space-saving (3mm x 3mm), 16-pin TQFN, or a 14-pin TSSOP pack-age and are specified over the extended (-40°C to +85°C) temperature range.ApplicationsFeatures♦1024 Tap Positions♦Power-On Recall of Wiper Position from Nonvolatile Memory♦16-Pin (3mm x 3mm x 0.8mm) TQFN or 14-Pin TSSOP Package♦35ppm/°C End-to-End Resistance Temperature Coefficient♦5ppm/°C Ratiometric Temperature Coefficient ♦10kΩand 50kΩEnd-to-End Resistor Values♦Pin-Selectable SPI-Compatible Serial Interface or Up/Down Digital Interface ♦1µA (max) Standby Current♦Single +2.7V to +5.25V Supply Operation ♦Dual ±2.5V Supply OperationMAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometers________________________________________________________________Maxim Integrated Products1Ordering InformationPin Configurations19-3708; Rev 5; 4/10For pricing delivery, and ordering information please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .Selector Guide appears at end of data sheet.SPI is a trademark of Motorola, Inc.temperature range.+Denotes a lead(Pb)-free/RoHS-compliant package.*EP = Exposed pad.Ordering Information continued at end of data sheet.Gain and Offset AdjustmentLCD Contrast Adjustment Pressure SensorsLow-Drift Programmable Gain AmplifiersMechanical Potentiometer ReplacementM A X 5481–M A X 548410-Bit, Nonvolatile, Linear-Taper Digital PotentiometersABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

programmable voltage-dividers and the MAX5483/MAX5484 variable resistors feature 1024 tap points (10-bit resolution) (see the Functional Diagrams ). These devices consist of multi-ple strings of equal resistor segments with a wiper con-tact that moves among the 1024 points through a pin-selectable 3-wire SPI-compatible serial interface or up/down interface. The MAX5481/MAX5483 provide a total end-to-end resistance of 10k Ω, and the MAX5482/MAX5484 have an end-to-end resistance of 50k Ω. The MAX5481/MAX5482 allow access to the high, low, and wiper terminals for a standard voltage-divider configuration.MAX5481/MAX5482 ProgrammableVoltage-DividersThe MAX5481/MAX5482 programmable voltage-dividers provide a weighted average of the voltage between the H and L inputs at the W output. Both devices feature 10-bit resolution and provide up to 1024 tap points between the H and L voltages. Ideally,the V L voltage occurs at the wiper terminal (W) when all data bits are zero and the V H voltage occurs at the wiper terminal when all data bits are one. The step size (1 LSB) voltage is equal to the voltage applied across terminals H and L divided by 210. Calculate the wiper voltage V Was follows:Functional Diagrams (continued)MAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometerswhere D is the decimal equivalent of the 10 data bits writ-ten (0 to 1023), V HL is the voltage difference between the H and L terminals:The MAX5481 includes a total end-to-end resistance value of 10k Ωwhile the MAX5482 features an end-to-end resistance value of 50k Ω. These devices are not intended to be used as a variable resistor . Wiper cur-rent creates a nonlinear voltage drop in series with the wiper. To ensure temperature drift remains within speci-fications, do not pull current through the voltage-divider wiper. Connect the wiper to a high-impedance node.Figures 1 and 2 show the behavior of the MAX5481’s resistance from W to H and from W to L. This does not apply to the variable-resistor devicesMAX5483/MAX5484 Variable ResistorsThe MAX5483/MAX5484 provide a programmable resistance between W and L. The MAX5483 features a total end-to-end resistance value of 10k Ω, while the MAX5484 provides an end-to-end resistance value of 50k Ω. The programmable resolution of this resistance is equal to the nominal end-to-end resistance divided by 1024 (10-bit resolution). For example, each nominal segment resistance is 9.8Ωand 48.8Ωfor the MAX5483and the MAX5484, respectively.wiper position from the 1024 possible positions, result-ing in 1024 values for the resistance from W to L.Calculate the resistance from W to L (R WL ) by using the where D is decimal equivalent of the 10 data bits writ-ten, R W-L is the nominal end-to-end resistance, and R Z is the zero-scale error. Table 1 shows the values of R WL at selected codes for the MAX5483/MAX5484.Digital InterfaceConfigure the MAX5481–MAX5484 by a pin-selectable,3-wire, SPI-compatible serial data interface or an up/down interface.

This write-only interface contains three inputs: chip select (CS ), data in (DIN(U/D )), and data clock (SCLK(INC )). Drive CS low to load the data at DIN(U/D ) synchronously into the shift register on each SCLK(INC ) rising edge.The WRITE command (C1, C0 = 00) requires 24 clock cycles to transfer the command and data (Figure 4a).The COPY commands (C1, C0 = 10 or 11) use either eight clock cycles to transfer the command bits (Figure 4b) or 24 clock cycles with the last 16 data bits disre-garded by the device.After loading the data into the shift register, drive CS high to latch the data into the appropriate control regis-ter. Keep CS low during the entire serial data stream to avoid corruption of the data. Table 2 shows the com-mand decoding.Write Wiper RegisterData written to this register (C1, C0 = 00) controls the wiper position. The 10 data bits (D9–D0) indicate the position of the wiper. For example, if DIN(U/D ) = 00 00000000, the wiper moves to the position closest to L. If DIN(U/D ) = 11 1111 1111, the wiper moves closest to H.This command writes data to the volatile random access memory (RAM), leaving the NV register unchanged. When the device powers up, the data stored in the NV register transfers to the wiper register,moving the wiper to the stored position. Figure 5 shows how to write data to the wiper register.Table 2.

Write Wiper Register OperationM A X 5481–M A X 548410-Bit, Nonvolatile, Linear-Taper Digital Potentiometers Copy Wiper Register to NV RegisterThe copy wiper register to NV register command (C1,C0 = 10) stores the current position of the wiper to the NV register for use at power-up. Figure 6 shows how to copy data from wiper register to NV register. The oper-ation takes up to 12ms (max) after CS goes high to complete and no other operation should be performed until completion.Copy NV Register to Wiper RegisterThe copy NV register to wiper register (C1, C0 = 11)restores the wiper position to the current value stored in the NV register. Figure 7 shows how to copy data from the NV register to the wiper register.Digital Up/Down InterfaceFigure 8 illustrates an up/down serial-interface timing diagram. In digital up/down interface mode (SPI/UD =0), the logic inputs CS , DIN(U/D ), and SCLK(INC ) con-trol the wiper position and store it in nonvolatile memory (see Table 3). The chip-select (CS ) input enables the serial interface when low and disables the interface when high. The position of the wiper is stored in the nonvolatile register when CS transitions from low to high while SCLK(INC ) is high.When the serial interface is active (CS low), a high-to-low (falling edge) transition on SCLK(INC ) increments or decrements the internal 10-bit counter depending on the state of DIN(U/D ). If DIN(U/D ) is high, the wiper increments. If DIN(U/D ) is low, the wiper decrements.The device stores the value of the wiper position in the nonvolatile memory when CS transitions from low to high while SCLK(INC ) is high. The host system can disablethe serial interface and deselect the device without stor-ing the latest wiper position in the nonvolatile memory by keeping SCLK(INC ) low while taking CS high.Upon power-up, the MAX5481–MAX5484 load the value of nonvolatile memory into the wiper register, and set the wiper position to the value last stored.Figure 6. Copy Wiper Register to NV Register OperationFigure 7. Copy NV Register to Wiper Register OperationMAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometersStandby ModeThe MAX5481–MAX5484 feature a low-power standby mode. When the device is not being programmed, it enters into standby mode and supply current drops to 0.5µA (typ).Nonvolatile MemoryThe internal EEPROM consists of a nonvolatile register that retains the last value stored prior to power-down.The nonvolatile register is programmed to midscale at the factory. The nonvolatile memory is guaranteed for 50 years of wiper data retention and up to 200,000wiper write cycles.Power-UpUpon power-up, the MAX5481–MAX5484 load the data stored in the nonvolatile wiper register into the volatile wiper register, updating the wiper position with the data stored in the nonvolatile wiper register.Applications InformationThe MAX5481–MAX5484 are ideal for circuits requiring digitally controlled adjustable resistance, such as LCD contrast control (where voltage biasing adjusts the dis-play contrast), or programmable filters with adjustable gain and/or cutoff frequency.Positive LCD Bias ControlFigures 9 and 10 show an application where a voltage-divider or a variable resistor is used to make an adjustable, positive LCD-bias voltage. The op amp pro-vides buffering and gain to the voltage-divider network made by the programmable voltage-divider (Figure 9) or to a fixed resistor and a variable resistor (see Figure 10).Programmable Gain and Offset AdjustmentFigure 11 shows an application where a voltage-divider and a variable resistor are used to make a programma-ble gain and offset adjustment.Figure 8.

General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, andMAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and onereceiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize E MI andreduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them totransmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA ofsupply current when unloaded or fully loaded with disableddrivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consumeonly 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature thatguarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-loadreceiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, whilethe MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________Applications Low-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level Translators Transceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features o For Fault-Tolerant Applications MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 Transceiver MAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers o For Space-Constrained Applications MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 Transceivers MAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 Package MAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe Receivers MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-485/RS-422 Transmitters o For Multiple Transceiver Applications MAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters o For Fail-Safe Applications MAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceiverso For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kVESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 Transceivers For pricing, delivery, and ordering information, please contact Maxim Direct at1-888-629-4642, or visit Maxim Integrated’s website at .______________________________________________________________Selection Table19-0122; Rev 10; 9/14PARTNUMBERHALF/FULL DUPLEX DATA RATE (Mbps) SLEW-RATE LIMITED LOW-POWER SHUTDOWN RECEIVER/DRIVER ENABLE QUIESCENT CURRENT (μA) NUMBER OF RECEIVERS ON BUS PIN COUNT MAX481Half 2.5No Yes Yes 300328MAX483Half 0.25Yes Yes Yes 120328MAX485Half 2.5No No Yes 300328MAX487Half 0.25Yes Yes Yes 1201288MAX488Full 0.25Yes No No 120328MAX489Full 0.25Yes No Yes 1203214MAX490Full 2.5No No No 300328MAX491Full 2.5No No Yes 3003214MAX1487 Half 2.5No No Yes 2301288Ordering Information appears at end of data sheet.找电子元器件上宇航军工MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-LimitedRS-485/RS-422 TransceiversPackage Information For the latest package outline information and land patterns, go to .

MH500 IQ Specs●Btu per burner- 515,000●CFM per burner- 3200●Fuel consumption per burner- 3.65 Gal/h●Recommended fuel consumption- K-1 Kerosene or No.1 Diesel●Operating power per burner- ~115 V, 1-PH, 60Hz 24 A (MAX 82 A)●Weight per burner- 357 lbs●Nozzles per burner- 2 GPH 60` Delavan Type A & 1 GPH 60` Delavan Type W ●Operating fuel pressure- 145 PSI/ 1000 kpa/ 10 barOverviewThe IQ system is a design that allows for the simplicity and ease ofoperation. At start up the IQ system will calibrate for the ambient air temperature and elevation to determine the air to fuel ratio setting for theair band. There are no more calibrations needed after this point and the IQsystem will recalculate the airband adjustment as ambient temperaturechanges.Control Screen Flickering/ Turning off & On❏The screen is a 12 volt system and receives power from the transformer box next to the IQ controller. Check power at the two terminal wires (blk & white) going into the right side of the IQ control. Check all connections on the main PC board and fuses.❏Check the Voltage regulator in the control box below Image (A). Make sure all voltage is proper.❏Make sure the rocker switch on the heater outlet door is working (Picture below).The switch is a two pole switch that closes once the door is opened. Power is sent to the screen for illumination.❏❏❏If the problem persists and power at the converter box showing 12 volts to the screen, then replace the screen.Engine Does Not Run**M axi Heat 500IQ will not start ( The engine will crank over ,but not run) Isuzu GensetNote:I f the unit has a shocker valve, check the value and make sure the shocker is open.** ❏Ensure the unit has enough fuel.❏Go through and check all the connections and most importantly check the emergency shutdown connection to make sure the connection is secure.(IsuzuEngine Timer Module-921432/ Cat C1.5 T4F- 650302)❏If all connections are secure then check to see if the engine is getting fuel.❏Pull the return line on the fuel pump and turn the engine over to see if the fuel pump is working correctly. Loosen the injector line at the injector to see if there is further fuel flow.❏The unit is getting fuel and the Fuel pump is working, find the fuel solenoid on the engine. Check the fuel shut off solenoid to ensure plunger retracts (example “A”, solenoid plunger retracts from voltage on hold wire)❏If the pump works when an auxiliary power source is applied then trace through wiring for loss of voltage. Power is pulled from the engine starter and goesthrough the temp and oil pressure switches. Check schematic for further testing.❏Burner Cycles On & Off**Maxi Heat 500IQ has one burner that will begin to run and then shuts down for High Temp Fault. ( Message appears on the IQ screen).**❏Each burner or both cycling on and off indicates that there is a possibility of backpressure. Back pressure occurs when the flow of heat is restricted and notmoved which accumulates at the outlet or in the burner itself. Kinks in the ducting can cause this issue. Make sure the ducting is straight with limited bends and no elevated lifts or descending of the ducting.❏Check ducting for proper flow.❏Ensure the high limit sensor is working at the end of the outlet.❏Check the main blower fans connection and ensure it is turning on as needed.Faulty connections or loss of power can cause a stall in fan operation which inturn causes the heater to increase temperature.❏Make sure heat going into the area is ventilated so heat does not accumulate and raises temperature to increase output.Blower Fan Stops Circulating or gets a Red “X” over fan:**MH 500 IQ has a burner that will start up and the fan will not turn on. Fan not running will cause the unit to shut down.**❏When this fault occurs it is an indication the fan is losing power.❏Check all the circuits to the fan. Power comes from 120 plug in into the bottom of the IQ controller.❏Start with going to the IQ control box for the burner that is having the issue. Open the cover of the box and over to the side is a wrench icon, press it. After pressing the icon type the password 123 then press the Enter button. You can control the fan manually from this point.❏Note: If you turn the fan on manually and the fan doesn't run, then the motor for the fan could be faulty and need to be replaced (#107194) ❏If the fan runs while in manual mode then the fan is working and power going to fan is ok. The circuit into the IQ controller that controls the blower fan has a loose or faulty connection.❏Check the red terminal block at the bottom of the IQ controller (See examples below). 120 volts into the terminal block feeds the relay above it and into the fan circuit during the purge process.No Power To IQ Control**Maxi Heat 500IQ Controller does not turn on or has no power to the IQ box.**❏No power into the IQ controller will not activate the LCD screen for further operation. Make sure the door on the outlet (heat out of burner) side isopen. The micro switch in the corner of the door activates power to eachscreen. * Switch is a two pole switch, if one side fails then the other couldstill open and provide power to the other screen.*❏Check the relay in the transformer box next to the controller (Example “A”). Make sure connections are secure and the relay is functioningproperly.❏Check the heater element on top of the fuel water separator filter. If element shorts then it will draw too much amperage and not allow thescreen to power up.❏If the IQ controller has 12 volts on the two wire ( example “B” below) harnesses into the side of the controller. If the wire has 12 volts then thescreen needs to be replaced.❏Example “A”Example “B”❏Burner shuts off for “Burner Power Break” or will not turn on**Burner shuts off or always seeing “Burner Power Break “ fault on screen.**❏During the purge cycle at the initial start up the burner ignitor box receives all its power from the IQ controller. System is 120 volts and is used topower the burner and fuel system.❏“Power Break” refers to the break in power to the burner. Test for loss of voltage at the Ignitor box in the burner assembly. (See example “B”) ❏Terminal “N” & “L” are power in. If there is no voltage then check the IQ controller for power loss. Power into the controller red terminal blockdistributes voltage to the fan and burner.❏Check the red terminal block for power in and out (120 v). Make sure connections are secure.❏Check the 15 amp fuse on the left of the controller. (Example “C”). If it fails, replace it.❏Test for voltage into the power relay above the red terminal block. During purge power goes to relay and out into the thermal breaker. (Example“C”). If failed, replace it.Example “B”Reset Safety Thermostat fault:**Safety thermostat is a protection for the high limit. If the fan has failed or heater shut down incorrectly it creates trapped heat which trips the thermostat.**❏Look for the black cap on the heat exchanger below the main blower fan.(Example “A”)❏Remove the cap and you will expose a red button. This button isconnected to the safety thermostat and has to be reset. Push and hold forfive seconds.❏If the thermostat continues to trip then give it 5 to 10 minutes for the heat to dissipate.❏If the problem persists then replace the safety thermostat.❏Burner starts to smoke and build black smoke out of exhaust stack:** Black smoke is an indication the unit is not getting enough air, bad fuel or carbon build up in the chamber.**❏Make sure air setting is on a specified number that the IQ controller recommends at the time of start up. D O NOT adjust air setting duringoperation unless the IQ controller specifies. (Any change of ambienttemperature and elevation requires smaller or higher amounts of airmixture.)❏Check for any debris or material covering or blocking the air damper.Clean and clear.❏Check fuel pressure and maintain 140-145 PSI at the pump.❏Ensure fuel nozzle NO 1 & NO 2 are both clean and working correctly.Check the schematic for a list of wiring for each nozzle. IQ logic controlsboth nozzles to maintain temperature.❏Make sure the heat exchanger and burn chamber are clear of any soot build up. If there is a large amount of build up then take the burner apartand wash with hot water high pressure hose. Let the barrel air dry beforeusing.❏Make sure only NO 1 Diesel fuel is used. Any additives can cause more gel-like substances which will create fuel issues.Filters perengine option:MH 500IQ MCS W/ ISUZU T4F 3CE1BurnerFUEL FILTER (35MICRON) 107222 ****MH**\ 14-******EngineAIR FILTER 650290 ****MH**\ 14-****** OIL FILTER 22-000309 ****MH**\ 14-****** FUEL FILTER 22-000310 ****MH**\ 14-******FILTER KIT (ALLFILTERS) 108461 ****MH**\ 14-******MH 500IQ MCS W/ CAT 1.5 NA T4FFUEL FILTER (35MICRON ) 107222 ****MH**\ 14-******EngineAIR FILTER 102580 ****MH**\ 14-****** OIL FILTER 650304 ****MH**\ 14-****** FUEL FILTER 103155 ****MH**\ 14-******FILTER KIT (ALLFILTERS) 108464 ****MH**\ 14-******Oil Change Intervals:Caterpillar C1.5- Every 500 hoursIsuzu 3CE1- Every 500 hoursIsuzu T4F 3CE1 Parts:●Dipstick Tube EXT Assy- ( 100604 )●Starter-102465●AVR Board-103016●Stop Solenoid--22-000316●Stop Solenoid O Ring- 22-000329●Alternator Diode- 22-000324●Temp Switch- 22-000325●Oil Pressure Switch- 22-000326●Relay Assembly- 650423●Fuel Pump- 22-000317●Auto Shutdown Timer-921432●Filter Kit (Air Fuel & Oil)- 108959●Fuel Water Separator ( 35 Micron Fuel Filter)- 107222●Timer Module-921432Cat 1.5 T4F Parts:●Ignition Keys- 920474●Ignition/Cat- 920475●Hour Meter- 340014●Timer/Shutdown- 650302●Cat 1.5 Muffler-104867●Muffler Gasket- 650234● 3 way Fuel Gauge- 103205●Filter Kit (Air Fuel & Oil)- 108961●Fuel Water Separator ( 35 Micron Fuel Filter)- 107222●Timer Shutdown-650302*Check engine operators manual for specific recommended lubricants.*Additional warranty information & claim forms can be obtained on .*Please contact Allmand Tech line for additional help and troubleshooting @ (308)995-3431 / Parts (800) 562-1373.。

Goodman Manufacturing Company, L.P .5151 San Felipe, Suite 500, Houston, TX 77056© 2004, 2007, 2009 - 2011, 2014 - 2015 Goodman Manufacturing Company, L.P.USER’S INFORMATION MANUALP ACKAGE G AS -E LECTRICInstaller -Affix this manual, Installation Guide, and Warranty adjacent to the appliance.Owner -Read and keep all product literature in a safe place for future reference.RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.HI-116E 7/152S IGNAL W ORDSDear Homeowner, please recognize the following safety infor-mation. This information will alert you to the potential for per-sonal injury.- Indicate hazards or unsafe practices which result in severe personal injury or death.Before using this manual, check the serial plate for propermodel identification.The installation and servicing of this equipment must be performed by qualified, experienced technicians only.G ENERAL I NFORMATIONU NIT L OCATIONThis unit is approved only for an outdoor installation. See the installation instructions for the required clearances to the unit. It is important that safety measures are taken in the surrounding area of the unit.Gutters or deflectors must be installed on the roof to prevent water from shedding on the unit.1.An area must be available to reach the unit in a clear and unobstructed path.2.The unit area and the vicinity of any other gas appliances must be kept clear and free of combustible materials, gaso-line, and other flammable vapors and liquids. Also, do not store or use flammable items such as paint, varnish, or lac-quer in the area.3.The combustion air supply must not be contaminated by prod-ucts containing chlorine or fluorine, as they could corrode the heat exchanger. If you need further information on this sub-ject, contact your installing dealer or another qualified ser-vicer.4.Familiarize yourself with the controls that turn off the gas and electrical power to the unit.5.Establish a regular service and maintenance schedule to ensure efficient and safe operation of the unit.6.The unit must be placed where no runoff water from higher ground can collect in the unit.U NIT I NSTALLATIONExamine the unit installation to determine the following:1.The flue hood connector is in place and is physically sound without holes or excessive corrosion.2.The mounting pad support of the unit is sound.3.There are no obvious signs of deterioration of the unit.4.The burner flames are stable, soft and blue, (dust may cause orange tips but must not be yellow). The flames should ex-tend directly outward from the burner without curling, floating,or lifting off. To examine, turn on the electrical power and gas.Set the room temperature to the maximum setting.BurnerNOTE: If a strong wind is blowing, it may not be possible to perform the flame inspection.A IR REQUIREMENTSSince the gas/electric unit is installed completely in the outdoors, the depletion of combustion air is highly improbable. To ensure an adequate supply of combustion air, do not allow the combus-tion air inlet or the flue hood outlet to become blocked by leaves, snow, rubbish, or insect (wasps) nests. Never block the con-densing unit section in the winter with covers. Blocking of this section would prevent an adequate amount of combustion air from reaching the furnace section.Great care has been taken in the design and manufacture of your unit to provide for your comfort and safety. Be aware of the possibility that some problems with your unit or other gas-fired appliances could cause flue gases to be present in your building. These flue gases could include carbon monoxide.3T HERMOSTA TThis unit will not operate properly without a good quality, correctly installed thermostat. It is very important that the thermostat be located where it can best “sense” the average room temperature. Be sure the thermostat is not exposed to hot or cold drafts or to hot or cold spots on the wall, such as those received from outside walls, walls with pipes inside, or from openings into the attic. No matter the type or style, thermostat operation is basically the same. The most widely used types will control both heating and cooling functions and will have a Fan Switch with Auto and ON settings. On Auto, the Circulating Air Blower will cycle on/off, but if switched to ON it will run constantly.For Dual Fuel units (GPD/APD), a Dual Fuel thermostat with an outdoor temperature sensor is recommended for optimal opera-tion.IMPORTANT NOTE: To avoid the possibility of damage to the unit heat exchanger, do not set the thermostat fan switch to ON (constant fan operation) during the heating season without first consulting the installer of the unit or another qualified servicer. There are thermostats that automatically switch from Heating to Cooling, or with night setbacks. The night setback, or multiple setback type, will lower the temperature at night or during the day when the building is unoccupied.Propane (LP) Gas Installations OnlyFor units operating on propane gas, please review the following warnings before use.O PERATING INSTRUCTIONSH EATING S TART U PTo put your unit into operation, follow the steps listed below.1.Close the external manual gas shutoff valve.2.Turn off the electrical power to the unit.3.Set the room thermostat to the lowest possible setting.4.Remove the heat exchanger door on the side of the unit byremoving screws.5.This unit is equipped with an ignition device which automati-cally lights the burner. Do not try to light the burner by hand.6.Move the gas control switch to the OFF position. Do not useexcessive force.7.Wait five minutes to clear out any gas. Then smell for gas,including near the floor as some types of gas are heavier than air.8.If you smell gas following the five minute waiting period instep 7, immediately follow the instructions on the cover of this manual. If you do not smell gas after five minutes, move or rotate the gas control switch to the ON position. The switch should turn easily. Do not use excessive force.9.Reinstall the burner compartment door.10.Open the external manual gas shutoff valve.11.Turn on the electrical power to the unit.12.Adjust the thermostat to a setting above room temperature.13.After the burners are lit, set the thermostat to desired tem-perature.H EATING S HUT D OWNTo shut down operation, follow the steps listed below.1.Set the thermostat to the lowest setting.2.Turn OFF electrical power to the unit.3.Remove the heat exchanger door on the side of the unit byremoving screws.4.Move the gas control switch to the OFF position. Do not useexcessive force.5.Close the external manual gas shutoff valve.6.Reinstall the heat exchanger door.7.If cooling and/or air circulation is desired, turn ON the electri-cal power.C OOLING O PERATIONCooling operation may be obtained as follows:1.Place the room thermostat selector switch in the COOL po-sition (or AUTO, if available, and if automatic changeover from cooling to heating is desired).2.Set the room thermostat to the desired temperature.3.If cooling system does not energize, wait five minutes. Thesystem startup may be delayed by the short-cycle protector feature of the ignition control board. Check the manual reset devices on the rollout limit, as described in this manual.OUTLET Gas ValveOn/OffSelectorSwitchWhite-Rodgers Model 36F224SelectorSwitchINLET OUTLETWhite-Rodgers Model 36G22High RegulatorWhite-Rodgers Model 36G54Honeywell Model VR8215 (Single-Stage)S AFETY C IRCUITSA number of safety circuits are employed to ensure safe and proper unit operation. These circuits serve to control any poten-tial safety hazards and, as inputs in the monitoring and diagnosis of abnormal operation.S ECONDARY L IMITThe secondary limit control is located on the blower housing and monitors blower compartment temperatures. It is a normally closed (electrically), automatic reset, temperature activated sensor. This limit guards against overheating as a result of insufficient conditioned air passing over the heat exchanger. It deenergizes the gas valve if the blower fails.NOTE: If the power to the unit is interrupted during the heating cycle, it may cause the secondary limit to trip. Once the blower compartment temperature drops below the limit reset temperature, the limit will automatically reset.Secondary Limit ControlR OLLOUT L IMITThe rollout limit is a normally-closed (electrically), manual-reset, temperature-activated sensor. It is mounted on the burnerbracket and monitors the burner flame. If there is an improper draw of burner flames into the heat exchanger, the rollout limit will detect it and shut off gas flowing to the burners. Contact a qualified servicer to check the unit before resetting this device.Rollout Protection on Burner Bracket56C OMPRESSOR P ROTECTIOND EVICESThis gas/electric package unit includes components which are designed to protect the compressor against abnormal operat-ing conditions.NOTE: The operation of the indoor blower will not be affected by any compressor protection devices.If, during a call for cooling, the indoor fan runs and circulates room temperature air while the compressor and outdoor fan do not operate:1.Wait five minutes, as a protection device may be holding the compressor off.2.Check the room thermostat to see if it is correctly set.3.If the room thermostat is correctly set, call a qualified servicer to determine if one of the compressor protection devices has opened.S HORT -C YCLE P ROTECTORA short-cycle protector is built into the ignition control. Each time the compressor is off for less than 3 minutes, the short-cycle protector will delay compressor startup for up to 3 minutes. This protects the compressor from improper operation.On Dual Fuel units (GPD/APD), the short-cycle protector will delay the compressor 5 minutes.NOTE: These units are not designed to provide mechanical cooling at outdoor temperatures below 50°F. If low ambient cooling is needed, consult a qualified servicer.I GNITERThe unit has an electronic ignition device which lights the burners automatically. Never try to light the burners by hand. It also has an induced draft blower to exhaust combustion prod-ucts.I NDOOR A IR C IRCULATOR B LOWERKeep the blower access door panel in place except for inspec-tion and maintenance.R OUTINE M AINTENANCEIf you perform maintenance on the unit yourself, remember that certain mechanical and electrical knowledge, skills and tools are required to perform unit maintenance. Personal injury or death may result If you are not properly trained. You should call your installing dealer or place of purchase if you are uncertainabout your ability to perform maintenance.A NNUAL I NSPECTIONYour package unit should be inspected by a qualified installer,or service agency at least twice every year. This check should be performed before the heating and cooling seasons begin. This will ensure that adequate combustion air is being drawn and the vent system is working properly. Particular attention should be paid to the following items. Repair as necessary.•Check physical support of the unit. Ensure it is sound with-out any sagging, cracks, or gaps, around the base.•Check for obvious signs of deterioration of the unit.•Flue Hood and Combustion Air Inlet. Check for blockage (wasp nest, etc.) and corrosion.Flue Hood•Return Air Connection. Check for physical soundness and ensure that the connection is firmly sealed to the package unit casing.•Heat exchanger. Check for corrosion and/or obstructions within the heat exchanger passageways.•Burners. Check for proper ignition, burner flame, and flame sense.•Wiring. Check electrical connections for tightness and/or corrosion. Check wires for damage.•Filters. Check that filters are clean and in the proper place-ment in the unit or duct system.•Louvers. Inspect air inlet louvers inside the heat exchanger compartments. Ensure the area is clean and free of dirt and debris.R EPLACING OR C LEANING F ILTERIMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.A return air filter is not supplied with this unit; however, there must be a means of filtering the return air. The filter(s) may be located in the return air duct(s). Consult with your installing dealer for the actual location of the return air filter(s) in your unit.A dirty filter is the most common cause of inadequate heating or cooling performance. Filter inspection should be made at least every two months; more often if necessary because of local conditions and usage.Dirty throwaway filters should be discarded and replaced with a new, clean filter. Dirty permanent filters should be washed with water, thoroughly dried and sprayed with a filter adhesive before being reinstalled. (Filter adhesives may be found at many hard-ware stores.) Permanent filters should last several years.

Preeshl Quality Assurance Quality Assurance Reliability Lab Manager Executive DirectorConclusionThe MAX6100 successfully meets the quality and reliability standards required of all Maxim products. In addition, Maxim’s continuous reliability monitoring program ensures that all outgoing product will continue to meet Maxim’s quality and reliability standards.Table of ContentsI. ........Device Description V. ........Quality Assurance InformationII. ........Manufacturing Information VI. .......Reliability EvaluationIII. .......Packaging Information IV. .......Die Information.....AttachmentsI. Device DescriptionA. GeneralThe MAX6100 is a low-cost, low-dropout (LDO), micropower voltage references. This three-terminal reference has an output voltage option of 1.8V. It features a proprietary curvature-correction circuit and laser-trimmed, thin-filmresistors that result in a low temperature coefficient of 75ppm/°C (max) and an initial accuracy of ±0.4% (max). This device is specified over the extended temperature range (-40°C to +85°C).This series-mode voltage reference draws only 90µA of supply current and can source 5mA and sink 2mA of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, this device offers a supply current that is virtually independent of the supply voltage (with only a 4µA/Vvariation with supply voltage) and does not require an external resistor. Additionally, this internally compensated device does not require an external compensation capacitor and is stable with load capacitance. Eliminating the external compensation capacitor saves valuable board area in space-critical applications. Low dropout voltage and supply-independent, ultra-low supply current makes this device ideal for battery-operated, high-performance, low-voltage systems.The MAX6100 is available in a tiny 3-pin SOT23 packages.B.

Reliability EvaluationA. Accelerated Life TestThe results of the 135°C biased (static) life test are shown in Table 1. Using these results, the Failure Rate (λ) is calculated as follows:λ = 1 = 1.83 (Chi square value for MTTF upper limit)MTTFλ = 6.79 x 10-9λ = 6.79 F.I.T. (60% confidence level @ 25°C)This low failure rate represents data collected from Maxim’s reliability monitor program. In addition to routine production Burn-In, Maxim pulls a sample from every fabrication process three times per week and subjects it to an extended Burn-In prior to shipment to ensure its reliability. The reliability control level for each lot to be shipped as standard product is 59 F.I.T. at a 60% confidence level, which equates to 3 failures in an 80 piece sample. Maxim performs failure analysis on any lot that exceeds this reliability control level. Attached Burn-In Schematic (Spec. # 06-5630) shows the static Burn-In circuit. Maxim also performs quarterly 1000 hour life test monitors. This data is published in the Product Reliability Report (RR-1M).B. Moisture Resistance TestsMaxim pulls pressure pot samples from every assembly process three times per week. Each lot sample must meet an LTPD = 20 or less before shipment as standard product. Additionally, the industry standard 85°C/85%RH testing is done per generic device/package family once a quarter.C. E.S.D. and Latch-Up TestingThe RF24-7die type has been found to have all pins able to withstand a transient pulse of ±1500V, per Mil-Std-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device withstands a current of ±250mA.Table 1Reliability Evaluation Test ResultsMAX6100EURTEST ITEM TEST CONDITION FAILURE SAMPLE NUMBER OFIDENTIFICATION PACKAGE SIZE FAILURES Static Life Test (Note 1)Ta = 135°C DC Parameters 160 0Biased & functionalityTime = 192 hrs.Moisture Testing (Note 2)Pressure Pot Ta = 121°C DC Parameters SOT 77 0P = 15 psi. & functionalityRH= 100%Time = 168hrs.85/85 Ta = 85°C DC Parameters 77 0RH = 85% & functionalityBiasedTime = 1000hrs.Mechanical Stress (Note 2)Temperature -65°C/150°C DC Parameters 77 0Cycle 1000 Cycles & functionalityMethod 1010Note 1: Life Test Data may represent plastic DIP qualification lots.Note 2: Generic Package/Process dataAttachment #1TABLE II.

MAX483、MAX487、MAX488以及MAX489具有限摆率驱动器，可以减小EMI ，并降低由不恰当的终端匹配电缆引起的反射，实现最高250k b p s 的无差错数据传输。

M A X 481、MAX485、MAX490、MAX491、MAX1487的驱动器摆率不受限制，可以实现最高2.5Mbps 的传输速率。

这些收发器在驱动器禁用的空载或满载状态下，吸取的电源电流在120(A 至500(A 之间。

另外，MAX481、MAX483与MAX487具有低电流关断模式，仅消耗0.1µA 。

所有器件都工作在5V 单电源下。

驱动器具有短路电流限制，并可以通过热关断电路将驱动器输出置为高阻状态，防止过度的功率损耗。

接收器输入具有失效保护特性，当输入开路时，可以确保逻辑高电平输出。

MAX487与MAX1487具有四分之一单位负载的接收器输入阻抗，使得总线上最多可以有128个M A X 487/MAX1487收发器。

使用MAX488-MAX491可以实现全双工通信，而MAX481、MAX483、MAX485、MAX487与MAX1487则为半双工应用设计。
