The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps. These transceivers draw as little as 120µA supply current when unloaded or when fully loaded with disabled drivers (see Selection Table ). Additionally, the MAX481E, MAX483E, and MAX487E have a low-current shutdown mode in which they consume only 0.5µA. All parts operate from a single +5V supply. Drivers are short-circuit current limited, and are protected against excessive power dissipation by thermal shutdown circuitry that places their outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit. The MAX487E and MAX1487E feature quarter-unit-load receiver input impedance, allowing up to 128 transceivers on the bus. The MAX488E–MAX491E are designed for fullduplex communications, while the MAX481E, MAX483E, MAX485E, MAX487E, and MAX1487E are designed for halfduplex applications. For applications that are not ESD sensitive see the pin- and function-compatible MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487.

This controller,designed to reside either on the backplane or on the removable card, is used to protect a system from start-up damage when a card or board is inserted into a rack with the main system power supply turned on. The card’s discharged filter capacitors provide a low impedance that can momentarily cause the main power supply to collapse. The MAX4370 prevents this start-up condition by providing inrush current regulation during a programmable start-up period, allowing the system to stabilize safely. In addition, two on-chip comparators provide DualSpeed/BiLevel short-circuit protection and overcurrent protection during normal operation.The MAX4370 provides protection for a +3V to +12V single supply. An internal charge pump generates the controlled gate drive for an external N-channel MOS -FET power switch. The MAX4370 latches the switch off after a fault condition until an external reset signal clears the device. Other features include a status pin to indicate a fault condition, an adjustable overcurrent response time, and a power-on reset comparator.The MAX4370 is specified for the extended-industrial temperature range (-40°C to +85°C) and is available in an 8-pin SO package.ApplicationsHot Board InsertionSolid-State Circuit BreakerFeatureso DualSpeed/BiLevel Protection During Normal Operation o Inrush Current Regulated at Start-Up o Resides Either on the Backplane or on the Removable Card o Programmable Start-Up Period and Response Time o Allows Safe Board Insertion and Removal from Live Backplane o Protection for +3V to +12V Single Supplies o Latched Off After Fault Condition o Status Output Pino Internal Charge Pump Generates Gate Drive for External N-Channel MOSFETMAX4370Current-Regulating Hot-Swap Controller withDualSpeed/BiLevel Fault Protection________________________________________________________________Maxim Integrated Products1Typical Operating Circuit19-1472; Rev 0; 4/99Ordering InformationPin Configuration appears at end of data sheet.M A X 4370Current-Regulating Hot-Swap Controller with DualSpeed/BiLevel Fault Protection 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V IN = +2.7V to +13.2V, T A = -40°C to +85°C, unless otherwise noted.

Functional DiagramM A X 4370Current-Regulating Hot-Swap Controller with DualSpeed/BiLevel Fault Protection 8_______________________________________________________________________________________Detailed DescriptionThe MAX4370 is a circuit-breaker IC designed for hot-swap applications where a card or board is to be inserted into a rack with the main system power supply turned on. Normally, when a card is plugged into a live backplane, the card is discharged filter capacitors pro-vide a low impedance, which can momentarily cause the main power supply to collapse. The MAX4370 is designed to reside either in the backplane or in the removable card to provide inrush-current limiting and short-circuit protection. This is achieved using a charge pump as gate drive for an external N-channel MOSFET,an external current-sense resistor, and two on-chip comparators. Figure 1 shows the device’s functional diagram.The slow comparator response time and the start-up timer can be adjusted with external capacitors. The tim-ing components are optional; without them the part is set to its nominal values, as shown in the Electrical Characteristics.Start-Up PeriodCTIM sets the start-up period. This mode starts when the power is first applied to V IN if ON is connected to V IN , or at the rising edge of ON. In addition, the voltage at V IN must be above the undervoltage lockout for 150ms (see Undervoltage Lockout ).During start-up, the slow comparator is disabled and current limiting is provided two different ways:1)Slow ramping of the current to the load by controlling the external MOSFET gate voltage.2)Limiting the current to the load by regulating the volt-age across the external current-sense resistor.Unlike other circuit-breaker ICs, the MAX4370 hot-swap controller regulates the current to a preset level instead of completely turning off if an overcurrent occurs during start-up.In start-up mode, the gate drive current is limited to 100µA and decreases with the increase of the gate voltage (see Typical Operating Characteristics ). This allows the MAX4370 to slowly enhance the MOSFET. If the fast comparator detects an overcurrent, the gate voltage is momentarily discharged with a fixed 80µA current until the load current through the sense resistor (R SENSE ) decreases below its threshold point. This effectively regulates the turn-on current during start-up.Figure 2 shows the start-up waveforms. STAT goes high at the end of the start-up period if no fault condi-tion is present.Normal Operation (DualSpeed/BiLevel)In normal operation (after the start-up period has expired), protection is provided by turning off the exter-nal MOSFET when a fault condition is encountered.DualSpeed/BiLevel fault protection incorporates two comparators with different thresholds and response times to monitor the load current:1)Slow Comparator. This comparator has an externally set response time (20µs to seconds) and a fixed 50mV threshold voltage. The slow comparator ignores low-amplitude momentary current glitches.After an extended overcurrent condition, a fault is detected and the MOSFET gate is discharged.2)Fast Comparator. This comparator has a fixed response time and a higher 200mV threshold volt -age. The fast comparator turns off the MOSFET immediately after it detects a large amplitude event such as a short circuit.In each case, when a fault is encountered, the status pin (STAT) goes low and the MAX4370 stays latched off. Figure 3 shows the waveforms after a fault condi -tion.Figure 2. Start-Up WaveformsMAX4370Current-Regulating Hot-Swap Controller withDualSpeed/BiLevel Fault Protection_______________________________________________________________________________________9Slow ComparatorThe slow comparator is disabled at start-up while the external MOSFET is turning on. This allows the part to ignore the higher-than-normal inrush current charging the board capacitors (C BOARD ) when a card is first plugged in.If the slow comparator detects an overload current while in normal operation (after start-up is completed),it turns off the external MOSFET by discharging the gate capacitance with a 200µA current. The slow com-parator threshold is set at 50mV and has a default delay of 20µs (CSPD floating), allowing it to ignore power-supply glitches and noise. The response time can be lengthened with an external capacitor at CSPD (Figure 8).If the overcurrent condition is not continuous, the dura-tion above the threshold minus the duration below it must be greater than 20µs (or the external programmed value) for the device to trip. When the current is above the threshold, CSPD is charged with a 6µA current source; when the current is below the threshold, CSPD is discharged with a 6µA current source. A fault is detected when CSPD is charged to the trip point of 1.2V. A pulsing current with a duty cycle greater than50% (i.e., > 50% of the time the current is above the threshold level) will be considered a fault condition even if it is never higher than the threshold for more than the slow comparator’s set response time.Once the fault condition is detected, the STAT pin goes low and the device goes into latched mode. The GATE voltage discharge rate depends on the gate capaci-tance and the external capacitance at GATE.Fast ComparatorThe fast comparator behaves differently according to the operating mode. During start-up, the fast compara-tor is part of a simple current regulator. When the sensed current is above the threshold (V FC,TH =200mV), the gate is discharged with a 80µA current source. When the sensed current drops below the threshold, the charge pump turns on again. The sensed current will rise and fall near the threshold due to the fast comparator and charge-pump propagation delay.The gate voltage will be roughly saw-tooth shaped, and the load current will present a 20% ripple. The ripple can be reduced by adding a capacitor from GATE to GND. Once C BOARD is completely charged, the load current drops to its normal operating levels. If the sensed current is still high after the start-up timer expires, the MOSFET gate is discharged completely.In normal operation (after start-up), the fast comparator is used as an emergency off switch. If the load current reaches the fast comparator threshold, the device immediately forces the MOSFET off completely by dis-charging the GATE with a 200µA current. This can occur in the event of a serious current overload or a dead short. Given a 1000pF gate capacitance and 12V gate voltage, the MOSFET will be off in less than 60µs.Any additional capacitance connected between GATE and GND to slow down the turn-on time also increases the turn-off time.Latched Mode and ResetThe MOSFET driver of the MAX4370 stays latched off after a fault condition until it is reset by a negative-going pulse on the ON pin. Pulse ON low for 20µs (min), then high to restart after a fault. During start-up, a negative-going edge on ON will force the device to turn off the MOSFET and place the device in latched mode.Keep ON low for 20µs (min) to restart.Figure 3. Response to a Fault ConditionM A X 4370Current-Regulating Hot-Swap Controller with DualSpeed/BiLevel Fault Protection 10______________________________________________________________________________________Status OutputThe status output is an open-drain output that goes low when the part is:1)in start-up2)forced off (on = GND)3)in an overcurrent condition, or 4)latched off.STAT is high only if the part is in normal mode and no faults are present (Table 1). Figure 4 shows the STAT timing diagram.Over/Undervoltage LockoutsThe undervoltage lockout prevents the MAX4370 from turning on the external MOSFET until the input voltage at V IN exceeds the lockout threshold (2.25V min) for at least 150ms. The undervoltage lockout protects the external MOSFET from insufficient gate drive voltage.The 150ms timeout ensures that the board is fully plugged into the backplane and that V IN is stable.Voltage transients at V IN with voltages below the UVLO will reset the device and initiate a start-up sequence.The device also features a gate overvoltage lockout that prevents the device from restarting after a fault condition if the discharge has not been completed.V GATE must be discharged to below 0.1V before restarting. Since the MAX4370 does not monitor the output voltage, a start-up sequence can be initiated while the board capacitance is still charged.Gate Overvoltage ProtectionNewer-generation MOSFETs have an absolute maxi -mum rating of ±8V for the gate-to-source voltage (V GS ).To protect these MOSFETs, the MAX4370 limits the gate-to-drain (V GD ) to +7.5V with an internal zener diode. No protection is provided for negative V GD . If GATE can be discharged to GND faster than the output voltage, an external small-signal protection diode (D1)can be used, as shown in Figure 5.Table 1.

德州仪器MAX4372-MAX4372T 电流检测放大器用户手册说明书

General DescriptionThe MAX4372 low-cost, precision, high-side current-sense amplifier is available in a tiny, space-saving SOT23 5-pin package. Offered in three gain versions (T = 20V/V, F = 50V/V, and H = 100V/V), this device oper-ates from a single 2.7V to 28V supply and consumes only 30μA. It features a voltage output that eliminates the need for gain-setting resistors and is ideal for today’s notebook computers, cell phones, and other systems where battery/ DC current monitoring is critical.High-side current monitoring is especially useful in bat-tery-powered systems since it does not interfere with the ground path of the battery charger. The input common-mode range of 0 to 28V is independent of the supply volt-age and ensures that the current-sense feedback remains viable even when connected to a 2-cell battery pack in deep discharge.The user can set the full-scale current reading by choos-ing the device (T, F, or H) with the desired voltage gain and selecting the appropriate external sense resistor. This capability offers a high level of integration and flex-ibility, resulting in a simple and compact current-sense solution. For higher bandwidth applications, refer to the MAX4173T/F/H data sheet.Applications●Power-Management Systems●General-System/Board-Level Current Monitoring●Notebook Computers●Portable/Battery-Powered Systems●Smart-Battery Packs/Chargers●Cell Phones●Precision-Current Sources Features●Low-Cost, Compact Current-Sense Solution●30μA Supply Current● 2.7V to 28V Operating Supply●0.18% Full-Scale Accuracy●0.3mV Input Offset Voltage●Low 1.5Ω Output Impedance●Three Gain Versions Available• 20V/V (MAX4372T)• 50V/V (MAX4372F)• 100V/V (MAX4372H)●High Accuracy +2V to +28V Common-Mode Range,Functional Down to 0V, Independent of SupplyVoltage●Available in a Space-Saving 5-Pin SOT23 Packageand 3 x 2 UCSP™ (1mm x 1.5mm) Package Ordering Information appears at end of data sheet.UCSP is a trademark of Maxim Integrated Products, Inc.19-1548; Rev 5; 5/11+Denotes lead(Pb)-free/RoHS-compliant package.T = Tape and reel.*Note: Gain values are as follows: 20V/V for the T version,50V/V for the F version, and 100V/V for the H version.

This feature allows the monitoring of current flow out of a battery in deep discharge, and also enables high-side current sensing at voltages far in excess of the supply voltage (V CC).Current flows through the sense resistor, generating a sense voltage (Figure 1. Functional Diagram). Since A1’s inverting input is high impedance, the voltage on the negative terminal equals V IN - V SENSE. A1 forces its positive terminal to match its negative terminal; therefore, the voltage across R G1 (V IN - V1-) equals V SENSE. This creates a current to flow through R G1 equal to V SENSE/ R G1. The transistor and current mirror amplify the current by a factor of β. This makes the current flowing out of the current mirror equal to:I M = β V SENSE/R G1A2’s positive terminal presents high impedance, so this current flows through R GD, with the following result:V2+ = R GD β x V SENSE/R G1R1 and R2 set the closed-loop gain for A2, which ampli-fies V2+, yielding:V OUT = R GD x β x V SENSE/R G1 (1 + R2/R1)The gain of the device equals:OUT SEN G1SE RGD x (1 + R2/R1)V V/Rβ=Applications Information Recommended Component ValuesThe MAX4372 operates over a wide variety of current ranges with different sense resistors. Table 1 lists com-mon resistor values for typical operation of the MAX4372.Choosing R SENSEGiven the gain and maximum load current, select R SENSE such that V OUT does not exceed V CC - 0.25V or 10V. To measure lower currents more accurately, use a high value for R SENSE. A higher value develops a higher sense volt-age, which overcomes offset voltage errors of the internal current amplifier.In applications monitoring very high current, ensure R SENSE is able to dissipate its own I2R losses. If the resistor’s rated power dissipation is exceeded, its value may drift or it may fail altogether, causing a differential voltage across the terminals in excess of the absolute maximum ratings.Figure 1.

Not internally connected.Using a PC Board Trace as R SENSEIf the cost of R SENSE is an issue and accuracy is not criti-cal, use the alternative solution shown in Figure 2. This solution uses copper PC board traces to create a sense resistor. The resistivity of a 0.1in wide trace of 2oz copper is about 30mΩ/ft. The resistance temperature coefficient of copper is fairly high (approximately 0.4%/°C), so sys-tems that experience a wide temperature variance must compensate for this effect. In addition, self-heating intro-duces a nonlinearity error. Do not exceed the maximum power dissipation of the copper trace.For example, the MAX4372T (with a maximum load cur-rent of 10A and an R SENSE of 5mΩ) creates a full-scale V SENSE of 50mV that yields a maximum V OUT of 1V. R SENSE, in this case, requires about 2in of 0.1in wide copper trace.UCSP Applications InformationFor the latest application details on UCSP construction, dimensions, tape carrier information, printed circuit board techniques, bump-pad layout, and recommended reflow temperature profile, as well as the latest information on reliability testing results, go to the Maxim’s website at /ucsp to find the Application Note: UCSP—A Wafer-Level Chip-Scale Package.Figure 2.

Low-Cost, Micropower, High-Side Current-Sense Amplifier + Comparator + Reference ICs
General Description
The MAX4373/MAX4374/MAX4375 low-cost, micropower, high-side current-sense supervisors contain a highside current-sense amplifier, bandgap reference, and comparator with latching output. They feature a voltage output that eliminates the need for gain-setting resistors, making them ideal for today’s notebook computers, cell phones, and other systems where battery/DC current monitoring is critical. High-side current monitoring is especially useful in battery-powered systems since it does not interfere with the ground path of the battery charger. The 0 to +28V input common-mode range is independent of the supply voltage, which ensures that the current-sense feedback remains viable even when connected to a battery pack in deep discharge. The comparator output of the MAX4373/MAX4374/ MAX4375 is latched to provide a turn-off flag that doesn’t oscillate. In addition, the MAX4374/MAX4375 contain a second comparator for use in window-detection functions. The MAX4373/MAX4374/MAX4375 are available in three different gain versions (T = +20V/V, F = +50V/V, H = +100V/V) and use an external sense resistor to set the sensitivity of the input voltage to the load current. These features offer a high level of integration, resulting in a simple and compact currentsense solution. The MAX4373/MAX4374/MAX4375 operate from a single +2.7V to +28V supply and consume 50µA. They are specified for the extended operating temperature range (-40°C to +85°C) and are available in 8-pin and 10-pin µMAX packages.

高端电流检测放大器性能分析 MAX4372

高端电流检测放大器性能分析 MAX4372 MAX4173 MAX4080文章发布人：gxy 共193人阅读文字大小：[ 大中小 ] 文字背景色：在讨论器件功能时，检流放大器可以看作一个输入级浮空的仪表/差分放大器。

这意味着即使器件采用VCC=3.3V或5V单电源供电，在输入共模电压远高于电源电压的条件下，器件仍然能够正常放大差分输入信号。

检流放大器的共模电压可以很高，例如可以高达28V(MAX4372和MAX4173)或76V(MAX4080和MAX4081)。

检流放大器的这一特性使其非常适合高端电流检测应用，这类应用往往需要对高压侧检流电阻两端的微小电压进行放大，并馈入到低压ADC或低压模拟控制环路进行处理。

这种情况下，通常需要在信号源端(例如检流电阻两端)对电流检测信号进行滤波。

可以采用差分滤波器(图1)滤除负载电流和检流电压的“毛刺”，也可以采用共模滤波器(图2)以增强在出现共模电压尖峰或瞬时过压时的ESD 保护能力。

合理选择元件构建滤波器，如果元件选择不当，则会引入一些无法预知的失调电压和增益误差，降低电路性能。

滤波器的选择MAX4173检流放大器如图3所示，该器件的检流电阻可直接连接到芯片的RS+和RS-端。

器件内部的运算放大器将检流电阻两端的差分电压恢复成RG1两端的差分电压，即ILOAD×RSENSE=VSENSE=IRG1×RG1。

然后，内部电流镜对电流IRG1进行电平转换和放大，产生输出电流IRGD。

MAX4173的内部电路中RGD=12kΩ，而RG1=6kΩ。

因此，由于RGD和RG1为片上电阻，实际阻值会因不同的半导体工艺而产生多达±30%的差异。

但是，因为最终增益精度取决于RGD和RG1的比例，所以可以很好地控制增益，并在生产过程中灵活调整。

构建差分/共模滤波器(如图1和图2所示)时，需要在检流电阻的RSENSE+和RSENSE-端与器件的RS+和RS-引脚之间接入串联电阻，此时相当于改变了芯片的RG1和RG2。

Output supply current values are specified with no output load present. The supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section. See Figure 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through Figure 15 for total V DD1 and V DD2 supply currents as a function of data rate for ADuM1400W /ADuM1401W /ADuM1402W channel configurations. 3 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed. 4 The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.5 t PHL propagation delay is measured from the 50% level of the falling edge of the V Ix signal to the 50% level of the falling edge of the V Ox signal. t PLH propagation delay is measured from the 50% level of the rising edge of the V Ix signal to the 50% level of the rising edge of the V Ox signal.6 t PSK is the magnitude of the worst-case difference in t PHL or t PLH that is measured between units at the same operating temperature, supply voltages, and output load within the recommended operating conditions.7 Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposing sides of the isolation barrier.8 CM H is the maximum common-mode voltage slew rate that can be sustained while maintaining V O > 0.8 V DD2. CM L is the maximum common-mode voltage slew rate that can be sustained while maintaining V O < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient magnitude is the range over which the common mode is slewed.9 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current for a given data rate.Data SheetADuM1400/ADuM1401/ADuM1402 Rev.

in a XYZ direction.Pleasepay attention to when spacing parts around the mechanism floating part.12.1.2When designing,please ensure there is no gap with disc entrance height position between the CL-C01 and the finish product.This will avoid damaging the disc.This will also avoid increasing disc moving load while inserting and ejecting the disc.12.1.3 Please make sure the disc guide is positioned not to touch the lever protecting doubleloading in the finished product design.12.1.4Please design the unit to avoid resonance causing vibration etc.when fixing the CL-C01 tothe case of the finished product.And also when you install the unit into the car.This will avoid bad oscillation resistive performance.12.1.5Please design the finished product to be dustproof.This will avoid lower the pick-up sensitivity etc.12,2Electrical Caution12.2.1Please never use electrical parts over the recommended rating etc.12.2.2Signal of the optical pick-up is high impedance.So,especially avoid designing the opticalpick-up close to the distal signal of the microcomputer,s clock etc.12.2.3Please pay attention to the position of FPC connector when designing your servo PCB toavoid FPC to be contorted.

and the FPCs more than necessary.13,7Fundamentally,play is not guaranteed with a 8cm disc if an adapter is used.Please avoid using an adapter.13,8Since the actuator of the OPTIMA-725C2 used a powerful magnet,the pick-up characteristics may be subjected by a magnetic object brought into close proximity.On the bottom of the gap between the actuator cover and the objective lens,an objective lens driving magnet is installed,prevent the gap from catching foreign objects.13,9When the objective lens is fouled,the characteristics of the OPTIMA-725C2 may be degraded (reduction of light output,for example).In such a case,clean the lens with a lint freecotton stick or the like soaked in the cleaning liquid JCB B-4 NO.2(manufactured by Nippon Membo) in such a manner that the delicate wires supporting the lens(bobbin) are notdisturbed.◆Similar instructions and precautions for cleaning the objective lens should be advisedto CD player users.◆Commercially available lens cleaners are not advisable for this purpose.Recognition of this specifications:Please return the recognized specifications within a month from the issued date.It isover a month from the issed date,we will think that

registered on every rising clock edge during t RC (min).Values are shown per module bank.2.The specified values are valid when data inputs (DQ’s)are stable during t RC (min.).3.All AC characteristics are shown for device level.An initial pause of 100µs is required after power-up,then a Precharge All Banks command must be given followed by 8Auto Refresh (CBR)cycles before the Mode Register Set Operation can begin.4.AC timing tests have V IL =0.4V and V IH =2.4V with the timing referenced to the 1.4V crossover point.The transitiontime is measured between V IH and V IL .All AC measurements assume t T =1ns with the AC output load circuit shown.Specific tac and toh parameters are measured with a 50pF only,without any resistive termination and with a input signal of 1V /ns edge rate between 0.8V and 2.0V.5.If clock rising time is longer than 1ns,a time (t T /2-0.5)ns has to be added to this parameter.6.Rated at 1.5V7.If t T is longer than 1ns,a time (t T -1)ns has to be added to this parameter.8.Any time that the refresh Period has been exceeded,a minimum of two Auto (CBR)Refresh commands must begiven to “wake-up”the device.9.Self Refresh Exit is a synchronous operation and begins on the 2nd positive clock edge after CKE returns high.Self Refresh Exit is not complete until a time period equal to t RC is satisfied once the Self Refresh Exit command is registered.10.Referenced to the time which the output achieves the open circuit condition,not to output voltage levels.11.t DAL is equivalent to t DPL +t RP .1.4VCLOCKINPUT OUTPUT50pFI/OZ=50Ohm+1.4V

MAX3086ECSD-T中文资料

General Description
The MAX3080E–MAX3089E are ±15kV electrostatic discharge (ESD)-protected, high-speed transceivers for RS485/RS-422 communication that contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3080E/MAX3081E/MAX3082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 115kbps. The MAX3083E/MAX3084E/MAX3085E offer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX3086E/MAX3087E/ MAX3088Es’ driver slew rates are not limited, making transmit speeds up to 10Mbps possible. The MAX3089E’s slew rate is selectable between 115kbps, 500kbps, and 10Mbps by driving a selector pin with a single three-state driver. All devices feature enhanced ESD protection. All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model. These transceivers typically draw 375µA of supply current when unloaded, or when fully loaded with the drivers disabled. All devices have a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus. The MAX3082E/MAX3085E/MAX3088E are intended for halfduplex communMAX3083E/MAX3084E/MAX3086E/MAX3087E are intended for full-duplex communications. The MAX3089E is selectable between half-duplex and full-duplex operation. It also features independently programmable receiver and transmitter output phase via separate pins.

MAX4474EUA中文资料

General DescriptionThe MAX4464/MAX4470/MAX4471/MAX4472/MAX4474family of micropower op amps operate from a single +1.8V to +5.5V supply and draw only 750nA of supply current. The MAX4470 family feature ground-sensing inputs and Rail-to-Rail ®output. The ultra-low supply current, low-operating voltage, and rail-to-rail output capabilities make these operational amplifiers ideal for use in single lithium ion (Li+), or two-cell NiCd or alka-line battery systems.The rail-to-rail output stage of the MAX4464/MAX4470/ MAX4471/MAX4472/MAX4474 amplifiers is capable of driving the output voltage to within 4mV of the rail with a 100k Ωload, and can sink and source 11mA with a +5V supply. These amplifiers are available in both fully com-pensated and decompensated versions. The single MAX4470, dual MAX4471, and the quad MAX4472 are unity-gain stable. The single MAX4464 and the dual MAX4474 are stable for closed-loop gain configurations of ≥+5V/V. These amplifiers are available in space-sav-ing SC70, SOT23, µMAX, and TSSOP packages.ApplicationsFeatureso Ultra-Low 750nA Supply Current Per Amplifier o Ultra-Low +1.8V Supply Voltage Operation o Ground-Sensing Input Common-Mode Range o Outputs Swing Rail-to-Railo Outputs Source and Sink 11mA of Load Current o No Phase Reversal for Overdriven Inputs o High 120dB Open-Loop Voltage Gain o Low 500µV Input Offset Voltage o 9kHz Gain-Bandwidth Product (MAX4470/MAX4471/MAX4472)o 40kHz Gain-Bandwidth Product (MAX4464/MAX4474)o 250pF (min) Capacitive Load Capability o Available in Tiny 5-Pin SC70 and 8-Pin SOT23PackagesMAX4464/MAX4470/MAX4471/MAX4472/MAX4474Single/Dual/Quad, +1.8V/750nA, SC70,Rail-to-Rail Op Amps________________________________________________________________Maxim Integrated Products 1Pin Configurations19-2021; Rev 2; 2/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.Selector GuideBattery-Powered SystemsPortable Instrumentation Pagers and Cellphones Micropower ThermostatsElectrometer Amplifiers Solar-Powered Systems Remote Sensor Active Badges pH MetersM A X 4464/M A X 4470/M A X 4471/M A X 4472/M A X 4474Single/Dual/Quad, +1.8V/750nA, SC70, Rail-to-Rail Op Amps 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Compensation for Feedback Node CapacitanceApplications InformationGround SensingThe common-mode input range of the MAX4470 family extends down to ground, and offers excellent common-mode rejection. These devices are guaranteed not to undergo phase reversal when the input is overdriven.Power Supplies and LayoutThe MAX4470 family operates from a single +1.8V to +5.5V power supply. Bypass power supplies with a 0.1µF ceramic capacitor placed close to the V DD pin. Ground layout improves performance by decreasing the amount of stray capacitance and noise at the op amp ’s inputs and outputs. To decrease stray capacitance, mini-mize PC board lengths and resistor leads, and place external components close to the op amps ’ pins.BandwidthThe MAX4470/MAX4471/MAX4472 are internally compensated for unity-gain stability and have a typical gain-bandwidth of 9kHz. The MAX4464/MAX4474 have a 40kHz typical gain-bandwidth and are stable for a gain of +5V/V or greater.StabilityThe MAX4464/MAX4470/MAX4471/MAX4472/MAX4474maintain stability in their minimum gain configuration while driving capacitive loads. Although this product family is primarily designed for low-frequency applica-tions, good layout is extremely important because low-power requirements demand high-impedance circuits.The layout should also minimize stray capacitance at the amplifier inputs. However some stray capacitance may be unavoidable, and it may be necessary to add a 2pF to 10pF capacitor across the feedback resistor as shown in Figure 2. Select the smallest capacitor value that ensures stability.Chip InformationMAX4470/MAX4464 TRANSISTOR COUNT: 147MAX4471/MAX4474 TRANSISTOR COUNT: 293MAX4472 TRANSISTOR COUNT: 585PROCESS: BiCMOSMAX4464/MAX4470/MAX4471/MAX4472/MAX4474Rail-to-Rail Op Amps______________________________________________________________________________________11M A X 4464/M A X 4470/M A X 4471/M A X 4472/M A X 4474Rail-to-Rail Op AmpsS C 70, 5L .E P SPackage Information(The package drawing(s) in this data sheet may not reflect the most current specifications.

需要的基本知识
本手册假定您具有自动化工程领域的常识。此外，还需要知道如何在 Windows 2000 或 XP 操作系统下使用计算机或具有相似功能的设备（例如，编程设备）。因为 S7-400 使用 STEP 7 基本软件进行组态，所以您还需熟知如何使用该软件。可在“使用 STEP 7 编程” 手册中获取此方面知识。尤其是在与安全相关的领域内使用 S7-400 时，要仔细阅读“安装”手册附录中有关电子控制器安全的注意事项。
