lm2903工作原理

lm2903工作原理
LM2903是一种双运算放大器，常用于模拟和数字电路中。

它由两个相互独立的运算放大器组成。

每个运算放大器都具有两个输入端和一个输出端。

两个运算放大器具有相同的工作原理。

每个运算放大器的工作原理如下：
1. 差分输入：每个运算放大器有两个输入端，分别称为非反相输入端（+IN）和反相输入端（-IN）。

当电压在非反相输入端上升时，输出电压也会上升；当电压在反相输入端上升时，输出电压则下降。

2. 开环增益：当输入电压在一定范围内变化时，输出电压会经过放大。

LM2903的开环增益是固定的，约为200倍左右。

3. 负反馈：为了稳定运算放大器的工作，需要将一部分输出电压反馈到输入端。

具体而言，将输出端引出的信号经过电阻网络反馈到反相输入端。

这种负反馈会减小增益，但能提高稳定性和线性度。

4. 输入阻抗和输出阻抗：LM2903的输入阻抗较高，约为
100MΩ，输出阻抗较低，约为100Ω。

这样可以避免对输入和输出电路的干扰，提高信号传输质量。

5. 供电电压：LM2903通常工作在+5V至+30V的供电电压范围内。

此外，芯片还具有过电流保护和静态电保护功能，以确
保可靠的工作。

总之，LM2903的工作原理是基于运算放大器的反馈机制实现对输入电压的放大，并通过负反馈提高稳定性和线性度。

它在模拟和数字电路中具有广泛的应用。

Description The LM2901/2903 series comparators consist of four and two independent precision voltage comparators with very low input offset voltage specification. They are designed to operate from a single power supply over a wide range of voltages; however operation from split power supplies is also possible. They offer low power supply current independent of the magnitude of the power supply voltage.The LM2901/2903 series comparators are designed to directly interface with TTL and CMOS. When operating from both plus and minus power supplies, the LM2901/2903 series comparators will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.The dual devices are available in SO-8, TSSOP-8, and MSOP-8, and the quad devices available in SO-14 and TSSOP-14 with industry standard pinouts. Both use green mold compound as standard.Features•Wide Power Supply Range: ▪ Single Supply: 2V to 36V ▪ Dual Supplies: ±1.0V to ±18V•Very Low Supply Current Drain—Independent of Supply Voltage ▪ LM2903: 0.6mA ▪ LM2901: 0.9mA• Low Input Bias Current: 25nA • Low Input Offset Current: ±5nA •Typical Offset Voltage: ▪ Non-A Device: 2mV ▪ A Device: 1mV• Common-Mode Input Voltage Range Includes Ground• Differential Input Voltage Range Equal to the Power Supply Voltage•Low Output Saturation Voltage: ▪ LM2903: 200mV at 4mA ▪ LM2901: 100mV at 4mA• Output Voltage Compatible with TTL, MOS and CMOS• Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) •Halogen and Antimony Free. “Green” Device (Note 3)Pin Assignments(Top View)SO-8/TSSOP-8/MSOP-81OUT V CC2IN-2IN+1IN-1IN+GND2OUTLM2903/ LM2903A(Top View)SO-14/TSSOP-141OUT 3OUT GND4IN+3IN-3IN+4IN-2OUTV CC2IN-2IN+1IN-1IN+4OUTLM2901/ LM2901ANotes: 1.

Like most comparators, the series can easily oscillate if the output lead is inadvertently allowed to capacitive couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as the comparators change states. Standard PC board layout is helpful as it reduces stray input-output coupling. Reducing the input resistors to <10kΩreduces the feedback signal levels. Finally, adding even a small amount (1.0mV to 10mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations, due to stray feedback, are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise and fall times, hysteresis is not required. All input pins of any unused comparators should be tied to the negative supply.The bias network of the LM2901/2903 series comparators establishes a quiescent current independent of the magnitude of the power supply voltage over the range of from 2.0V DC to 30V DC.The differential input voltage may be larger than V CC without damaging the device. Protection should be provided to prevent the input voltages from going negative more than -0.3V DC (@ +25°C). An input clamp diode can be used as shown in the applications section.The output of the LM2901/2903 series comparators is the uncommitted collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output ORing function. An output pull-up resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage applied to the V CC terminal of LM2901/2903 series comparator package. The output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used).The amount of current the output device can sink is limited by the drive available (which is independent of V CC) and the β of this device. When the maximum current limit is reached (approximately 16mA), the output transistor will come out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the approximately 60ΩR SAT of the output transistor. The low offset voltage of the output transistor (1.0mV) allows the output to clamp essentially to ground level for small load currents.Typical Application Circuit (V CC = 5.0V DC )Typical Application Circuit(V CC = 5.0V DC) (continued)Typical Application Circuit (V CC = 5.0V DC ) (continued)Ordering Information (Note 15)LM290X X XXX - 13ChannelGrade3 : Dual PackingPackageS : SO-813 : Tape & Reel1 : Quad A : Low V IOBlank : Normal S14 : SO-14T14 : TSSOP-14M8: MSOP-8TH: TSSOP-8Part Number Package CodePackaging 13” Tape and ReelQuantity Part Number SuffixLM2901T14-13 T14 TSSOP-14 2500/Tape & Reel -13 LM2901AT14-13 T14 TSSOP-14 2500/Tape & Reel -13 LM2901S14-13 S14 SO-14 2500/Tape & Reel -13 LM2901AS14-13 S14 SO-14 2500/Tape & Reel -13 LM2903S-13 S SO-8 2500/Tape & Reel -13 LM2903AS-13 S SO-8 2500/Tape & Reel -13 LM2903AM8-13 M8 MSOP-8 2500/Tape & Reel -13 LM2903M8-13 M8 MSOP-8 2500/Tape & Reel -13 LM2903ATH-13 TH TSSOP-8 2500/Tape & Reel -13 LM2903TH-13THTSSOP-82500/Tape & Reel-13Note: 15.

Low power dual voltage comparator
LM193/A/293/A/393/A/2903
DESCRIPTION
The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0mV max. for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. The LM193 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM193 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.

lm2903工作原理

lm2903工作原理
LM2903是一种双路比较器，它的工作原理如下：
1. 输入阶段：LM2903有两个输入端，每个输入端都有一个电
压输入引脚。

一个输入端被标记为非反转输入（+），另一个
被标记为反转输入（-）。

在正常工作条件下，通常将非反转
输入端连接到一个参考电压源，而将反转输入端连接到被比较的信号源。

2. 比较阶段：根据非反转输入端的电压与反转输入端的电压之间的比较结果，输出端给出相应的电平。

如果非反转输入端电压大于反转输入端电压，则输出端的电平为高电平；如果非反转输入端电压小于反转输入端电压，则输出端的电平为低电平。

3. 输出阶段：输出端具有开漏结构，只能输出低电平或无连接状态。

要获取输出电压，需要将输出端连接到外部电源。

4. 连接方案：可以通过使用一个偏置电阻网络，将非反转输入端连接到参考电压源，以形成一个可调电压作为比较的参考阈值。

总的来说，LM2903的工作原理是通过比较两个输入端的电压
来产生相应的输出电平，从而实现对输入信号的比较判断。

M2943电源芯片资料

M2943电源芯片资料1、首先检查7pin所连接的电解电容(或者反馈线圈所连接的电解电容)，查看其容量是否符合要求，如该电容容量明显减小，更换后应该不起振的故障就能恢复;如该电容正常，进行下一步检查。

2、在电路板上单独给uc/uc的7pin加16v电压，测量其8pin是否有5v，如果测量8pin有5v电压存在，则说明此芯片没有问题;如没有5v电压，须将uc/uc拆下单独检查数据16v至7pin，测量8pin与否存有5v，如果仍然没5v，则可以证明芯片已经损毁;如果测量8pin存有5v存有，则必须就是与8pin相连接的外围元器件与地之间存有短路存有。

此步骤主要就是检测c/uc芯片本身与否损毁，如果芯片没损毁，基本可以排除故障出来在初级部分，可以展开下一步检查。

(附于：检测uc/uc芯片损毁是否的另一种方法为：在检测回去芯片外围元器件(或更改回去外围损毁的元器件)后，先连上电源开关管，提输出电测uc/uc的7pin电压，若电压在10—17v间波动，其余各脚分别也存有电压波动，则表明电路已起振，uc基本正常，若7脚电压高，其余管脚并无电压或电压不波动，则uc/uc纸机。

)3、检查次级侧，推测应该是次级由于输出过载或短路，导致电流增大，进而反映到初级侧使uc/uc芯片的3pin实现保护，这就需要对次级侧实现过流保护功能的电子元器件进行逐一测量，直至查出故障。

现将uc/uc芯片正常工作时主要引脚电压列于下面：1pin：1.5v ,2pin：2.5v ,3pin：0.v ,6pin：1.05v ,7pin：14.1v ,8pin：5 v。

芯片一般是指集成电路的载体，也是集成电路经过设计、制造、封装、测试后的结果，通常是一个可以立即使用的独立的整体。

“芯片”和“集成电路”这两个词经常混着使用，比如在大家平常讨论话题中，集成电路设计和芯片设计说的是一个意思，芯片行业、集成电路行业、ic行业往往也是一个意思。

实际上，这两个词有联系，也有区别。

specified devices are required,please contact the TI Sales Office/Distributors for availability and specifications.(3)Positive excursions of input voltage may exceed the power supply level.As long as the other voltage remains within the common-moderange,the comparator will provide a proper output state.The low input voltage state must not be less than−0.3V(or0.3V below the magnitude of the negative power supply,if used).(4)This input current will only exist when the voltage at any of the input leads is driven negative.It is due to the collector-base junction ofthe input PNP transistors becoming forward biased and thereby acting as input diode clamps.In addition to this diode action,there is also lateral NPN parasitic transistor action on the IC chip.This transistor action can cause the output voltages of the comparators to go to the V+voltage level(or to ground for a large overdrive)for the time duration that an input is driven negative.This is not destructive and normal output states will re-establish when the input voltage,which was negative,again returns to a value greater than−0.3V. (5)For operating at high temperatures,the LM393and LM2903must be derated based on a125°C maximum junction temperature and athermal resistance of170°C/W which applies for the device soldered in a printed circuit board,operating in a still air ambient.The LM193/LM193A/LM293must be derated based on a150°C maximum junction temperature.The low bias dissipation and the“ON-OFF”characteristic of the outputs keeps the chip dissipation very small(P D≤100mW),provided the output transistors are allowed to saturate.(6)Short circuits from the output to V+can cause excessive heating and eventual destruction.When considering short circuits to ground,the maximum output current is approximately20mA independent of the magnitude of V+.Copyright©1999–2013,Texas Instruments Incorporated Submit

devices which,like most comparators,can easily oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance.This shows up only during the output voltage transition intervals as the comparator change states.Power supply bypassing is not required to solve this problem.Standard PC board layout is helpful as it reduces stray input-output coupling. Reducing the input resistors to<10kΩreduces the feedback signal levels and finally,adding even a small amount(1.0to10mV)of positive feedback(hysteresis)causes such a rapid transition that oscillations due to stray feedback are not possible.Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used.If the input signal is a pulse waveform,with relatively fast rise and fall times,hysteresis is not required.All input pins of any unused comparators should be tied to the negative supply.The bias network of the LM193series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from2.0V DC to30V DC.It is usually unnecessary to use a bypass capacitor across the power supply line.The differential input voltage may be larger than V+without damaging the device(1).Protection should be provided to prevent the input voltages from going negative more than−0.3V DC(at25°C).An input clamp diode can be used as shown in Typical Applications.The output of the LM193series is the uncommitted collector of a grounded-emitter NPN output transistor.Many collectors can be tied together to provide an output OR'ing function.An output pull-up resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage which is applied to the V+terminal of the LM193package.The output can also be used as a simple SPST switch to ground(when a pull-up resistor is not used).The amount of current which the output device can sink is limited by the drive available(which is independent of V+)and theβof this device.When the maximum current limit is reached(approximately16mA),the output transistor will come out of saturation and the output voltage will rise very rapidly.The output saturation voltage is limited by the approximately60Ωr SAT of the output transistor.The low offset voltage of the output transistor(1.0mV)allows the output to clamp essentially to ground level for small load currents.Typical Applications(V+=5.0V DC)Figure17.Basic Comparator Figure18.Driving CMOS(1)Positive excursions of input voltage may exceed the power supply level.As long as the other voltage remains within the common-moderange,the comparator will provide a proper output state.The low input voltage state must not be less than−0.3V(or0.3V below the magnitude of the negative power supply,if used).8Submit Documentation Feedback Copyright©1999–2013,Texas Instruments IncorporatedLM193-N,LM2903-N,LM293-N,LM393-N SNOSBJ6E–OCTOBER1999–REVISED MARCH2013 (V+=5.0V DC)Figure19.Driving TTL Figure20.Squarewave Oscillator *For large ratios of R1/R2,D1can be omitted.Figure21.Pulse Generator Figure22.Crystal Controlled OscillatorV*=+30V DC+250mV DC≤V C≤+50V DC700Hz≤f o≤100kHzFigure23.Two-Decade High Frequency VCOCopyright©1999–2013,Texas Instruments Incorporated Submit Documentation Feedback9LM193-N,LM2903-N,LM293-N,LM393-NSNOSBJ6E–OCTOBER1999–REVISED (V+=5.0V DC)Figure24.Basic Comparator Figure25.Non-Inverting Comparator withHysteresisFigure26.Inverting Comparator with Hysteresis Figure27.Output StrobingFigure28.AND Gate Figure29.OR Gate10Submit Documentation Feedback Copyright©1999–2013,Texas Instruments IncorporatedLM193-N,LM2903-N,LM293-N,LM393-N SNOSBJ6E–OCTOBER1999–REVISED MARCH2013 (V+=5.0V DC)rge Fan-in AND Gate Figure31.Limit Comparatorparing Input Voltages of Opposite Figure33.ORing the OutputsPolarityFigure34.Zero Crossing Detector(Single Power Figure35.One-Shot MultivibratorSupply)Copyright©1999–2013,Texas Instruments Incorporated Submit Documentation Feedback11LM193-N,LM2903-N,LM293-N,LM393-NSNOSBJ6E–OCTOBER1999–REVISED (V+=5.0V DC)Figure36.Bi-Stable Multivibrator Figure37.One-Shot Multivibrator with Input LockOutFigure38.Zero Crossing Detector parator With a Negative ReferenceFigure40.Time Delay Generator12Submit Documentation Feedback Copyright©1999–2013,Texas Instruments IncorporatedLM193-N,LM2903-N,LM293-N,LM393-N SNOSBJ6E–OCTOBER1999–REVISED MARCH2013(V+=5.0V DC)Split-Supply Applications(V+=+15V DC and V−=−15V DC)Figure41.MOS Clock DriverCopyright©1999–2013,Texas Instruments Incorporated Submit Documentation Feedback13LM193-N,LM2903-N,LM293-N,LM393-NSNOSBJ6E–OCTOBER1999–REVISED REVISION HISTORYChanges from Revision D(March2013)to Revision E Page •Changed layout of National Data Sheet to TI format (13)14Submit Documentation Feedback Copyright©1999–2013,Texas Instruments IncorporatedPACKAGING INFORMATIONAddendum-Page 1(1) The marketing status values are defined as follows:ACTIVE: Product device recommended for new designs.LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.NRND: Not recommended for new designs.

LM193/LM293/LM393/LM2903Low Power Low Offset Voltage Dual ComparatorsGeneral DescriptionThe LM193series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0mV max for two comparators which were de-signed specifically to operate from a single power supply over a wide range of voltages.Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.These comparators also have a unique characteris-tic in that the input common-mode voltage range includes ground,even though operated from a single power supply voltage.Application areas include limit comparators,simple analog to digital converters;pulse,squarewave and time delay gen-erators;wide range VCO;MOS clock timers;multivibrators and high voltage digital logic gates.The LM193series was designed to directly interface with TTL and CMOS.When operated from both plus and minus power supplies,the LM193series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.The LM393and LM2903parts are available in National’s innovative thin micro SMD package with 8(12mil)large bumps.Advantagesn High precision comparatorsn Reduced V OS drift over temperature n Eliminates need for dual supplies n Allows sensing near groundn Compatible with

LM393and LM2903must be derated based on a 125˚C maximum junction temperature and a thermal resistance of 170˚C/W which applies for the device soldered in a printed circuit board,operating in a still air ambient.The LM193/LM193A/LM293must be derated based on a 150˚C maximum junction temperature.The low bias dissipation and the “ON-OFF”characteristic of the outputs keeps the chip dissipation very small (P D ≤100mW),provided the output transistors are allowed to saturate.Note 2:Short circuits from the output to V +can cause excessive heating and eventual destruction.When considering short circuits to ground,the maximum output current is approximately 20mA independent of the magnitude of V +.Note 3:This input current will only exist when the voltage at any of the input leads is driven negative.It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps.In addition to this diode action,there is also lateral NPN parasitic transistor actionL M 193/L M 293/L M 393/L M 2903 4Electrical Characteristics(Continued)on the IC chip.This transistor action can cause the output voltages of the comparators to go to the V+voltage level(or to ground for a large overdrive)for the time duration that an input is driven negative.This is not destructive and normal output states will re-establish when the input voltage,which was negative,again returns to a value greater than−0.3V.Note4:These specifications are limited to−55˚C≤T A≤+125˚C,for the LM193/LM193A.With the LM293all temperature specifications are limited to −25˚C≤T A≤+85˚C and the LM393temperature specifications are limited to0˚C≤T A≤+70˚C.The LM2903is limited to−40˚C≤T A≤+85˚C.Note5:The direction of the input current is out of the IC due to the PNP input stage.This current is essentially constant,independent of the state of the output so no loading change exists on the reference or input lines.Note6:The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than0.3V.The upper end of the common-mode voltage range is V+−1.5V at25˚C,but either or both inputs can go to36V without damage,independent of the magnitude of V+.Note7:The response time specified is for a100mV input step with5mV overdrive.For larger overdrive signals300ns can be obtained,see typical performance characteristics section.Note8:Positive excursions of input voltage may exceed the power supply level.As long as the other voltage remains within the common-mode range,the comparator will provide a proper output state.The low input voltage state must not be less than−0.3V(or0.3V below the magnitude of the negative power supply, if used).Note9:At output switch point,V O.1.4V,R S=0Ωwith V+from5V to30V;and over the full input common-mode range(0V to V+−1.5V),at25˚C.Note10:Refer to RETS193AX for LM193AH military specifications and to RETS193X for LM193H military specifications.Ordering

—PositiveTransition00570934LM193/LM293/LM393/LM29037Application HintsThe LM193series are high gain,wide bandwidth devices which,like most comparators,can easily oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance.This shows up only during the output voltage transition intervals as the comparator change states.Power supply bypassing is not required to solve this problem.Standard PC board layout is helpful as it reduces stray input-output coupling.Reducing the input re-sistors to <10k Ωreduces the feedback signal levels and finally,adding even a small amount (1.0to 10mV)of positive feedback (hysteresis)causes such a rapid transition that oscillations due to stray feedback are not possible.Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used.If the input signal is a pulse waveform,with relatively fast rise and fall times,hysteresis is not required.All input pins of any unused comparators should be tied to the negative supply.The bias network of the LM193series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 2.0V DC to 30V DC .It is usually unnecessary to use a bypass capacitor across the power supply line.The differential input voltage may be larger than V +without damaging the device (Note 8).Protection should be provided to prevent the input voltages from going negative more than −0.3V DC (at 25˚C).An input clamp diode can be used as shown in the applications section.The output of the LM193series is the uncommitted collector of a grounded-emitter NPN output transistor.Many collectors can be tied together to provide an output OR’ing function.An output pull-up resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage which is applied to the V +terminal of the LM193package.The output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used).The amount of current which the output device can sink is limited by the drive available (which is independent of V +)and the βof this device.When the maximum current limit is reached (approximately 16mA),the output transistor will come out of saturation and the output voltage will rise very rapidly.The output saturation voltage is limited by the ap-proximately 60Ωr SAT of the output transistor.The low offset voltage of the output transistor (1.0mV)allows the output to clamp essentially to ground level for small load currents.Typical Applications(V +=5.0V DC )Basic
