Note1.0INPUT AND OUTPUT STAGEThe rail-to-rail input stage of this family provides more flex-ibility for the designer.The LMV931/LMV932/LMV934use a complimentary PNP and NPN input stage in which the PNP stage senses common mode voltage near V−and the NPN stage senses common mode voltage near V+.The transition from the PNP stage to NPN stage occurs1V below V+.Since both input stages have their own offset voltage,the offset of the amplifier becomes a function of the input common mode voltage and has a crossover point at1V below V+.This V OS crossover point can create problems for both DC and AC coupled signals if proper care is not rge input signals that include the V OS crossover point will cause distortion in the output signal.One way to avoid such distor-tion is to keep the signal away from the crossover.For example,in a unity gain buffer configuration and with V S= 5V,a5V peak-to-peak signal will contain input-crossover distortion while a3V peak-to-peak signal centered at1.5V will not contain input-crossover distortion as it avoids the crossover point.Another way to avoid large signal distortion is to use a gain of−1circuit which avoids any voltage excursions at the input terminals of the amplifier.In that circuit,the common mode DC voltage can be set at a level away from the V OS cross-over point.For small signals,this transition in V OS shows up as a V CM dependent spurious signal in series with the input signal and can effectively degrade small signal parameters such as gain and common mode rejection ratio.To resolve this problem,the small signal should be placed such that it avoids the V OS cross-over point.In addition to the rail-to-rail performance,the output stage can provide enough output current to drive 600Ωloads.Because of the high current capability,care should be taken not to exceed the150˚C maximum junction temperature specification.2.0INPUT BIAS CURRENT CONSIDERATIONThe LMV931/LMV932/LMV934family has a complementary bipolar input stage.The typical input bias current(I B)is 15nA.The input bias current can develop a significant offset voltage.This offset is primarily due to I B flowing through the negative feedback resistor,R F.For example,if I B is50nA and R F is100kΩ,then an offset voltage of5mV will develop (V OS=I B x R F).Using a compensation resistor(R C),as shown in Figure1,cancels this effect.But the input offset current(I OS)will still contribute to an offset voltage in the same manner.Typical Applications3.0HIGH SIDE CURRENT SENSINGThe high side current sensing circuit(Figure2)is commonlyused in a battery charger to monitor charging current toprevent over charging.A sense resistor R SENSE is connectedto the battery directly.This system requires an op amp withrail-to-rail input.The LMV931/LMV932/LMV934are ideal forthis application because its common mode input range goesup to the rail.20032659FIGURE1.Canceling the Offset Voltage due to InputBias Current200326H0FIGURE2.High Side Current SensingLMV931Single/LMV932Dual/LMV934Quad13Typical Applications(Continued)4.0HALF-WAVE RECTIFIER WITH RAIL-TO-GROUND OUTPUT SWINGSince the LMV931/LMV932/LMV934input common mode range includes both positive and negative supply rails and the output can also swing to either supply,achieving half-wave rectifier functions in either direction is an easy task.All that is needed are two external resistors;there is no need for diodes or matched resistors.The half wave rectifier can have either positive or negative going outputs,depending on the way the circuit is arranged.In Figure 3the circuit is referenced to ground,while in Figure 4the circuit is biased to the positive supply.These configu-rations implement the half wave rectifier since the LMV931/LMV932/LMV934can not respond to one-half of the incom-ing waveform.It can not respond to one-half of the incoming because the amplifier can not swing the output beyond either rail therefore the output disengages during this half cycle.During the other half cycle,however,the amplifier achieves a half wave that can have a peak equal to the total supply voltage.R I should be large enough not to load the LMV931/LMV932/LMV934.5.0INSTRUMENTATION AMPLIFIER WITH RAIL-TO-RAIL INPUT AND OUTPUTSome manufactures make a non-“rail-to-rail”-op amp rail-to-rail by using a resistive divider on the inputs.The resistors divide the input voltage to get a rail-to-rail input range.The problem with this method is that it also divides the signal,so in order to get the obtained gain,the amplifier must have a higher closed loop gain.This raises the noise and drift by the internal gain factor and lowers the input impedance.Any mismatch in these precision resistors reduces the CMRR as well.The LMV981/LMV982is rail-to-rail and therefore doesn’t have these disadvantages.Using three of the LMV981/LMV982amplifiers,an instru-mentation amplifier with rail-to-rail inputs and outputs can be made as shown in Figure 5.In this example,amplifiers on the left side act as buffers to the differential stage.These buffers assure that the input impedance is very high and require no precision matched resistors in the input stage.They also assure that the differ-ence amp is driven from a voltage source.This is necessary to maintain the CMRR set by the matching R 1-R 2with R 3-R 4.The gain is set by the ratio of R 2/R 1and R 3should equal R 1and R 4equal R 2.With both rail-to-rail input and output ranges,the input and output are only limited by the supplyvoltages.Remember that even with rail-to-rail outputs,the output can not swing past the supplies so the combined common mode voltages plus the signal should not be greater that the supplies or limiting will occur.For additional applications,see National Semiconductor application notes AN–29,AN–31,AN–71,and AN–127.200326C3200326C2200326C4FIGURE 3.Half-Wave Rectifier with Rail-To-Ground Output Swing Referenced to
