MAX4590EAE-T中文资料
General DescriptionThe MAX4580/MAX4590/MAX4600 dual analog switches feature low on-resistance of 1.25Ωmax. On-resistance is matched between switches to 0.25Ωmax and is flat (0.3Ωmax) over the specified signal range. Each switch can handle Rail-to-Rail ®analog signals. The off-leakage current is only 2.5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automat-ic test equipment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays.The MAX4580 has two NC (normally closed) switches,the MAX4590 has two NO (normally open) switches,and the MAX4600 has one NC (normally closed) and one NO (normally open) switch.These switches operate from a +4.5V to +36V single supply or from ±4.5V to ±20V dual supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a +12V sin-gle supply or ±15V dual supplies.ApplicationsReed Relay Replacement Test EquipmentCommunication Systems PBX, PABX SystemsFeatureso Low On-Resistance (1.25Ωmax)o Guaranteed R ON Match Between Channels (0.25Ωmax)o Guaranteed R ON Flatness Over Specified Signal Range (0.3Ωmax)o Rail-to-Rail Signal Handlingo Guaranteed ESD Protection >2kV per Method 3015.7o Single-Supply Operation: +4.5V to +36V Dual-Supply Operation: ±4.5V to ±20V o TTL/CMOS-Compatible Control InputsMAX4580/MAX4590/MAX46001.25Ω, Dual SPST,CMOS Analog Switches________________________________________________________________Maxim Integrated Products119-1394; Rev 1; 6/03Ordering Information continued at end of data sheet.Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.Pin Configurations/Functional Diagrams/Truth TablesOrdering InformationFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 4580/M A X 4590/M A X 46001.25Ω, Dual SPST,CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings can cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+and V- should not exceed 44V. These protection diodes are not recommended when using a single supply.Figure 1.

MAX4395ESD+中文资料
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.

General DescriptionThe MAX6339 is a precision quad voltage monitor with microprocessor (µP) supervisory reset timing. The device can monitor up to four system supply voltages without any external components and asserts a single reset if any supply voltage drops below its preset threshold. The device significantly reduces system size and component count while improving reliability compared to separate ICs or discrete components.A variety of factory-trimmed threshold voltages are avail-able to accommodate different supply voltages and toler-ances with minimal external component requirements.The selection includes internally fixed options for monitor-ing +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.0V sup-plies with -5% and/or -10% tolerances. The device is also available with one or two user-adjustable threshold options if non-standard thresholds are desired (use exter-nal resistor-divider network).The quad monitor provides a single active-low reset out-put that is asserted when any monitored input is below its associated threshold. The output is open drain with a weak internal pullup (10µA) to IN2. Reset remains low for a reset timeout period (140ms min) after all voltages are above the selected thresholds. The output is valid as long as either the IN1 or IN2 input voltage remains > 1V.The MAX6339 is available in a small 6-pin SOT23 pack-age and operates over the extended (-40°C to +85°C)temperature range.________________________ApplicationsTelecommunications High-End PrintersDesktop and Network Computers Data Storage Equipment Networking Equipment Industrial Equipment Set-Top BoxesFeatures♦Monitors Four Power-Supply Voltages♦Precision Factory-Set Reset Threshold Options for +5.0V, +3.3V, +3.0, +2.5V, +1.8V, and -5.0V Supplies ♦User-Adjustable Voltage Monitoring Threshold Options ♦Low 55µA Supply Current♦Open-Drain RESET Output with 10µA Internal Pullup ♦140ms (min) Reset Timeout Period ♦RESET Valid to IN1 = 1V or IN2 = 1V♦Immune to Short Monitored Supply Transients ♦No External Components Required ♦Guaranteed from -40°C to +85°C ♦Small 6-Pin SOT23 PackageMAX6339Quad Voltage µP Supervisory Circuitin SOT Package________________________________________________________________Maxim Integrated Products 119-1756; Rev 3; 12/05Ordering Information*Insert the desired letter from the Selector Guide into the blank to complete the part number.

The device offers several internally trimmed undervoltage threshold options that minimize or eliminate the need for external components. Preset voltage monitoring options for +5.0V, +3.3V, +3.0V, +2.5V, +1.8V, and -5.0V make it ideal for telecommunications, desktop and notebook computers, high-end printers, data storage equipment,and networking equipment applications.The quad monitor/reset includes an accurate bandgap reference, four precision comparators, and a series of internal trimmed resistor-divider networks to set the fac-tory-fixed reset threshold options. The resistor networks scale the specified IN_ reset voltages to match the internal bandgap reference/comparator voltage. User-adjustable threshold options bypass the internal resis-tor networks and connect directly to one of the comparator inputs (an external resistor-divider network is required for threshold matching). All threshold volt-age options, fixed and adjustable, are indicated through a single-letter code in the product number (see the Selector Guide ).Each of the internal comparators has a typical hystere-sis of 0.3% with respect to its reset threshold. This built-in hysteresis improves the monitor’s immunity to ambient noise without significantly reducing threshold accuracy when an input sits at its specified reset volt-age. The MAX6339 is also designed to ignore short IN_transients. See the Typical Operating Characteristics for a glitch immunity graph.Applications InformationReset OutputThe MAX6339 RESET output is asserted low when any of the monitored IN_ voltages drop below its specified reset threshold (or above for -5V option) and remain low for the reset timeout period (140ms minimum) after all inputs exceed their thresholds (Figure 2). The output is open drain with a weak internal pullup to the moni-tored IN2 supply (10µA typ). For many applications no external pullup resistor is required to interface with other logic devices. An external pullup resistor to any voltage from 0 to +5.5V can overdrive the internal pullup if interfacing to different logic supply voltages (Figure 3). Internal circuitry prevents reverse current flow from the external pullup voltage to IN2.The MAX6339 is normally powered from the monitored IN2 supply when all input voltages are above their specified thresholds. When any supply drops below itsthreshold, the reset output is asserted and guaranteed to remain low while either IN1 or IN2 is above +1.0V.User-Adjustable ThresholdsThe MAX6339 offers several monitor options with user-adjustable reset thresholds. The threshold voltage at each adjustable IN_ input is typically 1.23V. To monitor a voltage > 1.23V, connect a resistor-divider network to the circuit as shown in Figure 4.V INTH = 1.23V x (R1 + R2) / R2or, solved in terms of R1:R1 = R2 ((VI NTH / 1.23V) - 1)Because the MAX6339 has a guaranteed input current of ±0.1µA on its adjustable inputs, resistor values up to 100k Ωcan be used for R2 with < 1% error.Unused InputsIf some monitor inputs are to be unused, they must be tied to a supply voltage greater in magnitude than their specified threshold voltages. For unused IN3 or IN4options with positive thresholds (fixed or adjustable),the inputs can be connected directly to the IN2 supply.For unused IN4 options with negative thresholds, the input must be tied to a more negative supply. The IN2input must always be used for normal operation (device power-supply pin). Unused pins cannot be connected to ground or allowed to float.Negative Voltage Monitoring Beyond -5VThe MAX6339 is offered with options to monitor -5V sup-plies with internally fixed thresholds. To monitor supplies more negative than -5V, a low-impedance resistor-divider network can be used external to the MAX6339 as shown in Figure 5. The current through the external resis-tor-divider should be greater than the input current for the -5V monitor options. For an input monitor current error of < 1%, the resistor-divider current should ≥ 2mA (for I IN4= 20µA max). Set R2 = 2.5k Ω. Calculate R1based on the desired V IN_reset threshold voltage, using the following formula:R1 = R2 ✕[(V INTH / V TH ) -1]where R2 ≤2.49k Ω, V INTH = desired threshold voltage and V TH is the internal threshold voltage.M A X 6339Quad Voltage µP Supervisory Circuit in SOT Package 6_______________________________________________________________________________________Figure 1.

All monitor inputs are immune to short supply transients. If higher immunity is desired in noisy applications, connect 0.1µF bypass capacitors from the IN2 input to ground. Additionally, capacitance can be added to IN1, IN3, and IN4 to increase their noise immunity.Chip InformationTRANSISTOR COUNT: 896PROCESS: BiCMOSFigure 4.

Dual/Triple-Voltage µP Supervisory Circuits
General Description
The MAX6351–MAX6360 microprocessor (µP) supervisors with multiple reset voltages significantly improve system reliability and accuracy compared to separate ICs or discrete components. If any input supply voltage drops below its associated preset threshold, all reset outputs are asserted. In addition, the outputs are valid as long as either input supply voltage remains greater than +1.0V. All devices in this series have an active-low debounced manual reset input. In addition, the MAX6358/MAX6359/ MAX6360 offer a watchdog-timer input with a 46.4s startup timeout period and a 2.9s timeout period. The MAX6355/MAX6356/MAX6357 offer an additional voltage monitor input to monitor a third voltage. The MAX6351 features two active-low, push-pull reset outputs, one is referenced to VCC1 and the other is referenced to VCC2. The MAX6353/MAX6356/MAX6359 offer an active-low, push-pull reset output referenced to VCC1. The MAX6354/MAX6357/MAX6360 offer an active-low, push-pull reset output referenced to VCC2. All these devices are offered with a wide variety of voltage threshold levels, as shown in the Voltage Threshold Levels table. They are available in 5- and 6-pin SOT23 packages and operate over the extended (-40°C to +85°C) temperature range.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
