1.8V, RRIO Operational Amplifiers
General Description
The LMV931/LMV932/LMV934 are low voltage, low power
operational amplifiers. LMV931/LMV932/LMV934 operate
from +1.8V to +5.5V 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 600Ω 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 ra-
tio, 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 600Ω 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 5-Pin SC70 and
SOT23 packages. The dual LMV932 are in 8-Pin MSOP and
SOIC packages and the quad LMV934 are in 14-Pin TSSOP
and SOIC packages. These small packages are ideal solu-
tions for area constrained PC boards and portable electronics
such as cellular phones and PDAs.

Application Note
INPUT AND OUTPUT STAGE
The rail-to-rail input stage of this family provides more flexi-
bility 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 distor-
tion 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 de-
pendent 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
600Ω loads. Because of the high current capability, care
should be taken not to exceed the 150°C maximum junction
temperature specification.
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
100kΩ, 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
HIGH SIDE CURRENT SENSING
The high side current sensing circuit (Figure 2) is commonly
used in a battery charger to monitor charging current to pre-
vent 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.

FIGURE 2. High Side Current Sensing
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 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 3 the circuit is referenced to ground, while in Figure
4 the circuit is biased to the positive supply. These configu-
rations 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 be-
cause 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 volt-
age. RI should be large enough not to load the LMV931/
LMV932/LMV934.

INSTRUMENTATION AMPLIFIER WITH RAIL-TO-RAIL
INPUT AND OUTPUT
Some 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 mis-
match 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 re-
sistors 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 sup-
plies or limiting will occur. For additional applications, see
National Semiconductor application notes AN–29, AN–31,
AN–71, and AN–127.
