General DescriptionThe MAX4389/MAX4390/MAX4392–MAX4396 family of op amps are unity-gain stable devices that combine high-speed performance, rail-to-rail outputs, and dis-able mode. These devices are targeted for applications where an input or an output is exposed to the outside world, such as video and communications.The MAX4389/MAX4390/MAX4392–MAX4396 operate from a single 4.5V to 11V supply or from dual ±2.25V to ±5.5V supplies. The common-mode input voltage range extends to the negative power-supply rail (ground in sin-gle-supply applications). The MAX4389/MAX4390/MAX4392–MAX4396 consume only 5.5mA of quinescent supply current per amplifier while achieving a 85MHz -3dB bandwidth, 27MHz 0.1dB gain flatness, and a 500V/µs slew rate. Disable mode sets the outputs to high impedance while consuming only 450µA of current.The MAX4389 single, MAX4393 dual, MAX4394 triple,and MAX4396 quad include disable capabilities. The MAX4389 and MAX4390 are available in ultra-small,6-pin SC70 packages.ApplicationsSet-Top BoxesSurveillance Video SystemsAnalog-to-Digital Converter Interface CCD Imaging Systems Digital Cameras Video-on-Demand Video Line DriverFeatures♦Low Cost ♦High Speed85MHz -3dB Bandwidth 27MHz 0.1dB Gain Flatness 500V/µs Slew Rate♦Single 4.5V to 11V or Dual ±2.25V to ±5.5V Operation♦Rail-to-Rail Outputs♦Input Common-Mode Range Extends to V EE ♦Low Differential Gain/Phase: 0.015%/0.015°♦Low Distortion at 5MHz-59dBc Spurious-Free Dynamic Range ♦High Output Drive: ±50mA ♦450µA Disable Capability(MAX4389/MAX4393/MAX4394/MAX4396)♦Space-Saving SC70, SOT23, µMAX, or TSSOP PackagesMAX4389/MAX4390/MAX4392–MAX4396Ultra-Small, Low-Cost, 85MHz Op Amps withRail-to-Rail Outputs and Disable________________________________________________________________Maxim Integrated Products 1Pin Configurations19-2322; Rev 3; 8/04For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering InformationTypical Operating CircuitOrdering Information continued at end of data sheet.Selector Guide appears at end of data sheet.M A X 4389/M A X 4390/M A X 4392–M A X 4396Ultra-Small, Low-Cost, 85MHz Op Amps with Rail-to-Rail Outputs and DisableABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Disable______________________________________________________________________________________11Detailed DescriptionThe MAX4389/MAX4390/MAX4392–MAX4396 are dual-supply, rail-to-rail, voltage-feedback amplifiers that employ current-feedback techniques to achieve 500V/µs slew rates and 85MHz bandwidths. Excellent harmonic distortion and differential gain/phase perfor-mance make these amplifiers an ideal choice for a wide variety of video and RF signal-processing applications.Applications InformationThe output voltage swings to within 200mV of each supply rail. Local feedback around the output stage ensures low open-loop output impedance to reducegain sensitivity to load variations. The input stage per-mits common-mode voltages to the negative supply and to within 2.25V of the positive supply rail.Choosing Resistor ValuesUnity-Gain ConfigurationThe MAX4389/MAX4390/MAX4392–MAX4396 are inter-nally compensated for unity gain. When configured for unity gain, a 24Ωresistor (R F ) in series with the feed-back path optimizes AC performance. This resistor improves AC response by reducing the Q of the paral-lel LC circuit formed by the parasitic feedback capaci-tance and inductance.M A X 4389/M A X 4390/M A X 4392–M A X 4396Ultra-Small, Low-Cost, 85MHz Op Amps with Rail-to-Rail Outputs and Disable 12______________________________________________________________________________________Video Line DriverThe MAX4389/MAX4390/MAX4392–MAX4396 are low-power, voltage-feedback amplifiers featuring large-sig-nal (2V P-P ) bandwidths of 90MHz and 0.1dB large-signal gain flatness of 24MHz. They are designed to minimize differential-gain error and differential-phase error to 0.015% and 0.015°, respectively. They have a 21ns settling time to 0.1%, 500V/µs slew rates, and out-put-current-drive capability of up to 50mA making them ideal for driving video loads.Inverting and Noninverting ConfigurationsSelect the gain-setting feedback (R F ) and input (R G )resistor values to fit your application. Large resistor val-ues increase voltage noise and interact with the amplifi-er’s input and PC board capacitance. This can generate undesirable poles and zeros and decrease bandwidth or cause oscillations. For example, a nonin-verting gain-of-two configuration (R F = R G ) using 2k Ωresistors, combined with 1pF of amplifier input capaci-tance and 1pF of PC board capacitance, causes a pole at 79.6MHz. Since this pole is within the amplifier band-width, it jeopardizes stability. Reducing the 2k Ωresis-tors to 100Ωextends the pole frequency to 1.59GHz,but could limit output swing by adding 200Ωin parallel with the amplifier’s load resistor (Figures 1a and 1b).Layout and Power-Supply BypassingThe MAX4389/MAX4390/MAX4392–MAX4396 operate from single 4.5V to 11V or from dual ±2.25V to ±5.5V supplies. Bypass each supply with a 0.1µF capacitor as close to the pin as possible.Maxim recommends using microstrip and stripline tech-niques to obtain full bandwidth. To ensure that the PC board does not degrade the amplifier’s performance,design it for a frequency greater than 1GHz. Pay care-ful attention to inputs and outputs to avoid large para-sitic capacitance. Whether or not you use a con-stant-impedance board, observe the following design guidelines:•Do not use wire-wrap boards; they are too inductive.•Do not use IC sockets; they increase parasitic cap-acitance and inductance.•Use surface-mount instead of through-hole compo-nents for better, high-frequency performance.•Use a PC board with at least two layers; it should be as free from voids as possible.•Keep signal lines as short and as straight as possi-ble. Do not make 90°turns; round all corners.Low-Power Disable ModeThe MAX4389/MAX4393/MAX4394/MAX4396 feature a disable function that allows the amplifiers to be placed in a low-power, high-output-impedance state. When the disable pin (DISABLE ) is active, the amplifier’s output impedance is 95k Ω. This high resistance and the low 2pF output capacitance make the MAX4389/MAX4390/MAX4392–MAX4396 in RF/video multiplexer or switch applications. For larger arrays, pay careful attention to capacitive loading (see the Output Capacitive Loading and Stability section).Output Capacitive Loading and StabilityThe MAX4389/MAX4390/MAX4392–MAX4396 are opti-mized for AC performance. They are not designed to drive highly reactive loads, which decrease phase mar-gin and may produce excessive ringing and oscillation.Figure 2shows a circuit that eliminates this problem.Figure 3is a graph of the Optimal Isolation Resistor (R S ) vs. Capacitive Load. Figure 4shows how a capac-itive load causes excessive peaking of the amplifier’s frequency response if the capacitor is not isolated from the amplifier by a resistor. A small isolation resistor (usually 10Ωto 15Ω) placed before the reactive load prevents ringing and oscillation. At higher capacitive loads, AC performance is controlled by the interaction of the load capacitance and the isolation resistor.Figure 5shows the effect of a 15Ωisolation resistor on closed-loop response.Figure 1b.

MAX485中文资料2009-11-28 14:49MAX485中文资料，MAX485 PDF,DATASHEET,电路图，通讯程序内容介绍：MAX481、MAX483、MAX485、MAX487-MAX491以及MAX1487是用于RS-485与RS-422通信的低功耗收发器，每个器件中都具有一个驱动器和一个接收器。

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250kbps 的无差错数据传输。

MAX481、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。

General Description The MAX3483, MAX3485, MAX3486, MAX3488,MAX3490, and MAX3491 are 3.3V , low-power transceivers forRS-485 and RS-422 communication. Each part containsone driver and one receiver. The MAX3483 and MAX3488feature slew-rate-limited drivers that minimize EMI andreduce reflections caused by improperly terminatedcables, allowing error-free data transmission at data ratesup to 250kbps. The partially slew-rate-limited MAX3486transmits up to 2.5Mbps. The MAX3485, MAX3490, andMAX3491 transmit at up to 10Mbps.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 both inputs are opencircuit.The MAX3488, MAX3490, and MAX3491 feature full-duplex communication, while the MAX3483, MAX3485, andMAX3486 are designed for half-duplex communication.Applications ●Low-Power RS-485/RS-422 Transceivers ●Telecommunications ●Transceivers for EMI-Sensitive Applications ●Industrial-Control Local Area NetworksFeatures●Operate from a Single 3.3V Supply—No Charge Pump!●Interoperable with +5V Logic ●8ns Max Skew (MAX3485/MAX3490/MAX3491)●Slew-Rate Limited for Errorless Data Transmission (MAX3483/MAX3488)●2nA Low-Current Shutdown Mode (MAX3483/MAX3485/MAX3486/MAX3491)●-7V to +12V Common-Mode Input Voltage Range ●Allows up to 32 Transceivers on the Bus ●Full-Duplex and Half-Duplex Versions Available ●Industry Standard 75176 Pinout (MAX3483/MAX3485/MAX3486)●Current-Limiting and Thermal Shutdown for Driver Overload Protection 19-0333; Rev 1; 5/19Ordering Information continued at end of data sheet.*Contact factory for for dice specifications.PARTTEMP .
