General DescriptionThe MAX6126 is an ultra-low-noise, high-precision, low-dropout voltage reference. This family of voltage refer-ences feature curvature-correction circuitry and high-stability, laser-trimmed, thin-film resistors that result in 3ppm/°C (max) temperature coefficients and an excellent ±0.02% (max) initial accuracy. The propri-etary low-noise reference architecture produces a low flicker noise of 1.3µV P-P and wideband noise as low as 60nV/√Hz (2.048V output) without the increased supply current usually found in low-noise references. Improve wideband noise to 35nV/√Hz and AC power-supply rejection by adding a 0.1µF capacitor at the noise reduction pin. The MAX6126 series mode reference operates from a wide 2.7V to 12.6V supply voltage range and load-regulation specifications are guaran-teed to be less than 0.025Ωfor sink and source cur-rents up to 10mA. These devices are available over the automotive temperature range of -40°C to +125°C.The MAX6126 typically draws 380µA of supply current and is available in 2.048V, 2.500V, 3.000V, 4.096V, and 5.000V output voltages. These devices also feature dropout voltages as low as 200mV. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, the MAX6126offers supply current that is virtually independent of supply voltage and does not require an external resis-tor. The MAX6126 is stable with 0.1µF to 10µF of load capacitance.The MAX6126 is available in the tiny 8-pin µMAX, as well as 8-pin SO packages.ApplicationsHigh-Resolution A/D and D/A Converters ATE EquipmentHigh-Accuracy Reference Standard Precision Current Sources Digital VoltmetersHigh-Accuracy Industrial and Process ControlFeatures♦Ultra-Low 1.3µV P-P Noise (0.1Hz to 10Hz, 2.048V Output)♦Ultra-Low 3ppm/°C (max) Temperature Coefficient ♦±0.02% (max) Initial Accuracy♦Wide (V OUT + 200mV) to 12.6V Supply Voltage Range ♦Low 200mV (max) Dropout Voltage ♦380µA Quiescent Supply Current ♦10mA Sink/Source-Current Capability ♦Stable with C LOAD = 0.1µF to 10µF ♦Low 20ppm/1000hr Long-Term Stability ♦0.025Ω(max) Load Regulation ♦20µV/V (max) Line Regulation♦Force and Sense Outputs for Remote SensingMAX6126Ultra-High-Precision, Ultra-Low-Noise,Series Voltage Reference________________________________________________________________Maxim Integrated Products1Pin ConfigurationOrdering Information19-2647; Rev 4; 7/04For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering Information continued at end of data sheet.M A X 6126Ultra-High-Precision, Ultra-Low-Noise, Series Voltage Reference 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

STABILITY vs. TIME (µMAX)TIME (hr)V O U T (V )Note 5:Many of the MAX6126 Typical Operating Characteristics are extremely similar. The extremes of these characteristics arefound in the MAX6126_21 (2.048V output) and the MAX6126_50 (5.000V output). The Typical Operating Characteristics of the remainder of the MAX6126 family typically lie between those two extremes and can be estimated based on their output voltages.MAX6126Series Voltage Reference______________________________________________________________________________________13Detailed DescriptionWideband Noise ReductionTo improve wideband noise and transient power-supply noise, add a 0.1µF capacitor to NR (Figure 1). Larger values do not improve noise appreciably. A 0.1µF NR capacitor reduces the noise from 60nV/√Hz to 35nV/√Hz for the 2.048V output. Noise in the power-supply input can affect output noise, but can be reduced by adding an optional bypass capacitor between IN and GND, as shown in the Typical Operating Circuit .Output BypassingThe MAX6126 requires an output capacitor between 0.1µF and 10µF. Locate the output capacitor as close to OUTF as possible. For applications driving switching capacitive loads or rapidly changing load currents, it is advantageous to use a 10µF capacitor in parallel with a 0.1µF capacitor. Larger capacitor values reduce tran-sients on the reference output.Supply CurrentThe quiescent supply current of the series-mode MAX6126 family is typically 380µA and is virtually inde-pendent of the supply voltage, with only a 2µA/V (max)variation with supply voltage.When the supply voltage is below the minimum speci-fied input voltage during turn-on, the device can drawup to 300µA beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on.Thermal HysteresisThermal hysteresis is the change of output voltage at T A = +25°C before and after the device is cycled over its entire operating temperature range. The typical ther-mal hysteresis value is 20ppm (SO package).Turn-On TimeThese devices typically turn on and settle to within 0.1% of their final value in 200µs to 2ms depending on the device. The turn-on time can increase up to 4ms with the device operating at the minimum dropout volt-age and the maximum load. A noise reduction capaci-tor of 0.1µF increases the turn-on time to 20ms.Output Force and SenseThe MAX6126 provides independent connections for the power-circuit output (OUTF) supplying current into a load, and for the circuit input regulating the voltage applied to that load (OUTS). This configuration allows for the cancellation of the voltage drop on the lines connect-ing the MAX6126 and the load. When using the Kelvin connection made possible by the independent current and voltage connections, take the power connection to the load from OUTF, and bring a line from OUTS to join the line from OUTF, at the point where the voltage accu-M A X 6126Series Voltage Reference 14______________________________________________________________________________________racy is needed. The MAX6126 has the same type of Kelvin connection to cancel drops in the ground return line. Connect the load to ground and bring a connection from GNDS to exactly the same point.Applications InformationPrecision Current SourceFigure 2 shows a typical circuit providing a precision current source. The OUTF output provides the bias cur-rent for the bipolar transistor. OUTS and GNDS sense the voltage across the resistor and adjust the current sourced by OUTF accordingly. For even higher preci-sion, use a MOSFET to eliminate base current errors.High-Resolution DAC and Reference froma Single SupplyFigure 3 shows a typical circuit providing the reference for a high-resolution, 16-bit MAX541 D/A converter.Temperature Coefficient vs. Operating Temperature Range for a 1 LSB MaximumErrorIn a data converter application, the reference voltage of the converter must stay within a certain limit to keep the error in the data converter smaller than the resolution limit through the operating temperature range. Figure 4shows the maximum allowable reference voltage tem-perature coefficient to keep the conversion error to less than 1 LSB, as a function of the operating temperature range (T MAX - T MIN ) with the converter resolution as a parameter. The graph assumes the reference voltage temperature coefficient as the only parameter affecting accuracy.In reality, the absolute static accuracy of a data con-verter is dependent on the combination of many para-meters such as integral nonlinearity, differential nonlinearity, offset error, gain error, as well as voltage reference changes.Figure 2.

威斯康星电机--MC-612充电调节器使用手册说明书

I.INTRODUCTIONThe microprocessor-controlled Max Charge MC-612 is the most advancedregulator available. Designed to continual-ly monitor battery voltage and automaticallyoptimize charging, the MC-612 uses up to 12 time and voltage increments to ensure your batteries receive a full charge quickly and safely.The MC-612 lets you choose from a variety of selectablepreset programs to best suit your charging needs. II t s U n i v e r s a l F a c t o r y P r og r a m a l l o w s y o u t o c o n n e c t t h e M C -612 t oy o u r a l t e r n a t o r r i g h t o u t o f t h e b o x .Six additional preset programs support most popular battery types, including stan-dard and deep-cycle flooded batteries, AGM, gel, and Optima (spiral wound) technologies, as well as special settings for systems supplying halogen lighting. An easy-to-use magnetic reed switch delivers quick, precise regulator adjustment.Should your charging system require individualized adjustment, the MC-612 provides additional advanced user-defined programming options.When used with optional alternator and battery temperature sensors, the MC-612 automatically monitors ambient alter-nator and battery temperatures and compensates by adjusting field output to match conditions. Alarm outputs connect to audible or visual alarms to provide warnings of dangerous system conditions .II. SAFETY CONSIDERATIONSBefore installing your MC-612 marine regulator, please take a moment to con-sider these guidelines for safe regulator installation. Failure to work safely could result in personal injury or damage to your electrical system.1.Always disconnect your battery banks and ensure that switches are “OFF”prior to installing your regulator.2.Remove loose-fitting clothing or jewelry, which could become entangled inyour motor or other machinery.3.Wear ANSI-approved safety glasses.4.DO NOT attempt to modify the regulator. Alterations could result in damage to your charging system, and will void your warranty.5.Do not attempt installation if tired or fatigued.6.Ensure the engine has cooled before initiating installation.7.Do not attempt installation while using alcohol or any medication that could impair your judgment or reaction time.8.Always use the right tool for the job. Improper tool use may damage the regulator or your boat, and could result in personal injury.9.Take time to read the manual. Equipment damage and possibleinjuries may result from an incomplete understanding of the installa-tion and operation of the MC-612 regulator. If you are unfamiliar with marine electrical systems, consult with a licensed marine electrician.Max Charge MC-612 Regulator Installation and Operator’s ManualThe following information is essential to the proper operation of your Max Charge regulator. Do not install or operate before review-ing the following:1.POSITIVE BATTERY SENSE WIRE- User supplied -- not in harness. This wire must be connected to the regulatorand to a source of positive battery voltage (see Figure 3 for mounting location) to provide proper regulator operation.The regulator WILL NOT WORK if the sense wire is not connected to the regulator or the voltage source. The Positive BATTERY SENSE WIRE MUST BE FUSED. A 1-amp ATC fuse and holder are included with the regulator and harness.2.GROUNDING- The Model MC-612 must be properly grounded to regulate accurately. The two ground wires locatedin the harness must be securely attached to their terminals and at the alternator’s preferred ground to ensure proper grounding. A grounding cable between the alternator and the system ground is strongly recommended.3.VOLTAGE READINGS- MC-612 digital circuitry is engineered to monitor battery charge state and automaticallycompensate for changes in battery voltage during operation. As a result, it is NOT unusual to see near-constant changes in the regulator’s Battery Voltage display. These voltage changes reflect the regulator’s ability to make precise corrections to optimize charging efficiency based on changes in system loads.5.ELECTRICAL TACHOMETERS- Many factory and aftermarket tachometers require an AC pulse from the alternatorto drive the tachometer. If you are using an electrical tachometer that is being driven off of your alternator's stator pulse, plug the white stator wire into the terminal provided on the regulator, and the tach feed into the Tach Out termi-nal. If you are not using the stator pulse to drive your tachometer, DO NOT plug the stator wire into the regulator's Stator connection.When using the alternator and regulator to drive your tachometer, there is a possibility that you will see surface volt-age creeping in excess of target voltage when batteries are fully charged and there is no load on the system. This occurs as a result of the regulator's effort to provide just enough voltage to keep the tachometer feed activated. This voltage creep can usually be reduced or eliminated by increasing the load on the batteries, ie., turning on a few cabin lights or cabin fans, until the batteries are allowed to accept charging voltage.4.DUAL-OUTPUT OPERATION- When using the MC-612 with a dual-output alternator it is essential that the regulatorsenses the largest battery bank. The positive Battery sense wire must be attached to the alternator output terminal connected to the larger battery bank or at the larger bank. If your system includes a large house battery and a smaller starting battery, there is the possibility that the smaller battery may see excess surface voltage during charging.5.ALTERNATOR & BATTERY TEMPERATURE SENSORS(optional)- Alternator Temperature Sensor monitors forover-temperature conditions at the alternator. If alternator temperatures outside of safe limits are detected, the regu-lator will reduce alternator output to 50% and will activate an alarm circuit. NOTE:This option is not intended to be used as part of regular operation. If circuit is activated, inspect and repair the system immediately. Optional Battery temperature sensing compensates for above- or below-normal battery temperatures by automatically adjusting charg-ing voltage. It is not unusual to see charging voltage rise safely above normal levels when battery temperatures are below 26°(C) or drop when temperatures exceed 26°(C).6.MAGNETIC REED SWITCH- Not all magnets are alike. You may find that one magnet will activate the reed switchwith little effort, while another similar magnet may require a bit of maneuvering to find the switch’s “sweet spot.” If you have difficulty adjusting program modes, be sure to check for the dot at the top of the LED between the second and third display digits to ensure that you are activating the switch.Figure1- Regulator wiring attachment. Figure3- Regulator terminal layout.Secure the 3/8" copper probe to a clean negative (-) battery terminal (seeFigure 6). The 20' leads may be shortened or extended, if needed.

Ultra-High-Precision, Ultra-Low-Noise, Series Voltage Reference
General Description
The MAX6126 is an ultra-low-noise, high-precision, lowdropout voltage reference. This family of voltage references feature curvature-correction circuitry and high-stability, laser-trimmed, thin-film resistors that result in 3ppm/°C (max) temperature coefficients and an excellent ±0.02% (max) initial accuracy. The proprietary low-noise reference architecture produces a low flicker noise of 1.3µVP-P and wideband noise as low as 60nV/√Hz (2.048V output) without the increased supply current usually found in low-noise references. Improve wideband noise to 35nV/ √ Hz and AC power-supply rejection by adding a 0.1µF capacitor at the noise reduction pin. The MAX6126 series mode reference operates from a wide 2.7V to 12.6V supply voltage range and load-regulation specifications are guaranteed to be less than 0.025Ω for sink and source currents up to 10mA. These devices are available over the automotive temperature range of -40°C to +125°C. The MAX6126 typically draws 380µA of supply current and is available in 2.048V, 2.500V, 3.000V, 4.096V, and 5.000V output voltages. These devices also feature dropout voltages as low as 200mV. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, the MAX6126 offers supply current that is virtually independent of supply voltage and does not require an external resistor. The MAX6126 is stable with 0.1µF to 10µF of load capacitance. The MAX6126 is available in the tiny 8-pin µMAX, as well as 8-pin SO packages.
