LMV931 Single / LMV932 Dual / LMV934 Quad 1.8V, RRIO Operational Amplifiers
General Description
The LMV931/LMV932/LMV934 are low voltage, low power operational amplifiers. LMV931/LMV932/LMV934 are guaranteed to operate from +1.8V to +5.0V supply voltages and have rail-to-rail input and output. LMV931/LMV932/LMV934 input common mode voltage extends 200mV beyond the supplies which enables user enhanced functionality beyond the supply voltage range. The output can swing rail-to-rail unloaded and within 105mV from the rail with 600 load at 1.8V supply. The LMV931/LMV932/LMV934 are optimized to work at 1.8V which make them ideal for portable two-cell battery powered systems and single cell Li-Ion systems. LMV931/LMV932/LMV934 exhibit excellent speed-power ratio, achieving 1.4MHz gain bandwidth product at 1.8V supply voltage with very low supply current. The LMV931/LMV932/ LMV934 are capable of driving a 600 load and up to 1000pF capacitive load with minimal ringing. LMV931/ LMV932/LMV934 have a high DC gain of 101dB, making them suitable for low frequency applications. The single LMV931 is offered in space saving SC70-5 and SOT23-5 packages. The dual LMV932 are in MSOP-8 and SOIC-8 packages and the quad LMV934 are in TSSOP-14 and SOIC-14 packages. These small packages are ideal solutions for area constrained PC boards and portable electronics such as cellular phones and PDAs.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics. Note 2: Human body model, 1.5k in series with 100pF. Machine model, 200 in series with 100pF. Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150C. Output currents in excess of 45mA over long term may adversely affect reliability. Note 4: The maximum power dissipation is a function of TJ(MAX) , JA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX)-T A)/JA. All numbers apply for packages soldered directly into a PC board. Note 5: Typical Values represent the most likely parametric norm. Note 6: All limits are guaranteed by testing or statistical analysis. Note 7: Connected as voltage follower with input step from V- to V+. Number specified is the slower of the positive and negative slew rates. Note 8: For guaranteed temperature ranges, see Input Common-Mode Voltage Range specifications. Note 9: Input referred, RL = 100k connected to V+/2. Each amp excited in turn with 1kHz to produce VO = 3VPP (For Supply Voltages <3V, VO = V+). Note 10: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. See Applications section for information of temperature derating of the device. Absolute Maximum Ratings indicated junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically.

Application Note
1.0 INPUT AND OUTPUT STAGE The rail-to-rail input stage of this family provides more flexibility for the designer. The LMV931/LMV932/LMV934 use 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 occurs 1V 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 at 1V below V+. This VOS crossover point can create problems for both DC and AC coupled signals if proper care is not taken. Large input signals that include the VOS crossover point will cause distortion in the output signal. One way to avoid such distortion is to keep the signal away from the crossover. For example, in a unity gain buffer configuration and with VS = 5V, a 5V peak-to-peak signal will contain input-crossover distortion while a 3V peak-to-peak signal centered at 1.5V 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 -1 circuit 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 VOS cross-over point. For small signals, this transition in VOS shows up as a VCM 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 VOS crossover point. In addition to the rail-to-rail performance, the output stage can provide enough output current to drive 600 loads. Because of the high current capability, care should be taken not to exceed the 150C maximum junction temperature specification. 2.0 INPUT BIAS CURRENT CONSIDERATION The LMV931/LMV932/LMV934 family has a complementary bipolar input stage. The typical input bias current (IB) is 15nA. The input bias current can develop a significant offset voltage. This offset is primarily due to IB flowing through the negative feedback resistor, RF. For example, if IB is 50nA and RF is 100k, then an offset voltage of 5mV will develop (VOS = IB x RF). Using a compensation resistor (RC), as shown in Figure 1, cancels this effect. But the input offset current (IOS) will still contribute to an offset voltage in the same manner.

Typical Applications
3.0 HIGH SIDE CURRENT SENSING The high side current sensing circuit (Figure 2) is commonly used in a battery charger to monitor charging current to prevent over charging. A sense resistor RSENSE is connected to the battery directly. This system requires an op amp with rail-to-rail input. The LMV931/LMV932/LMV934 are ideal for this application because its common mode input range goes up to the rail.

4.0 HALF-WAVE RECTIFIER WITH RAIL-TO-GROUND OUTPUT SWING Since the LMV931/LMV932/LMV934 input common mode range includes both positive and negative supply rails and the output can also swing to either supply, achieving halfwave 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 3 the circuit is referenced to ground, while in Figure 4 the circuit is biased to the positive supply. These configurations implement the half wave rectifier since the LMV931/ LMV932/LMV934 can not respond to one-half of the incoming 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. RI should be large enough not to load the LMV931/LMV932/LMV934.

FIGURE 4. Half-Wave Rectifier with Negative-Going Output Referenced to VCC 5.0 INSTRUMENTATION AMPLIFIER WITH RAIL-TO-RAIL INPUT AND OUTPUT Some manufactures make a non-"rail-to-rail"-op amp rail-torail 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 LMV931/LMV932/LMV934 is rail-to-rail and therefore doesn't have these disadvantages. Using three of the LMV931/LMV932/LMV934 amplifiers, an instrumentation 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 difference amp is driven from a voltage source. This is necessary to maintain the CMRR set by the matching R1-R2 with R3-R4. The gain is set by the ratio of R2/R1 and R3 should equal R1 and R4 equal R2. With both rail-to-rail input and output ranges, the input and output are only limited by the supply voltages. 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.
