Description
The LMV82x series of single, dual and quad
operational amplifiers offers low voltage operation
with rail-to-rail output swing. The LMV82x series
outperforms the industry standard LMV321
especially with regard to the gain bandwidth
product (5.5 MHz). The LMV821, LMV822 and
LMV824 are proposed with standard pinouts.

SO14
The LMV820, LMV823 and LMV825 include a
power-saving shutdown feature that reduces the
supply current to a maximum of 50 nA at 25°C.

1. All voltage values, except the differential voltage are with respect to the network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. Vcc-Vin must not exceed 6 V, Vin must not exceed 6 V.
4. The input current must be limited by a resistor in series with the inputs.
5. Vcc-V
6. Short-circuits can cause excessive heating and destructive dissipation.
7. R
8. Human body model: a 100 pF capacitor is discharged through a 1.5 kΩ resistor between two pins of the
device. This is done for all couples of pin combinations while other pins are floating.
9. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
pin combinations while other pins are floating.
10. Charged device model: all pins and package are charged together to the specified voltage and then
discharged directly to ground.

Application information LMV82x, LMV82xA
4 Application information
4.1 Operating voltages
The LMV82x can operate from 2.5 to 5.5 V. The devices’ parameters are fully specified for
2.5, 2.7 and 5 V power supplies. Additionally, the main specifications are guaranteed at
extended temperature ranges from -40° C to +125° C.
4.2 Input common mode range
The LMV82x devices have an input common mode range that includes ground. The input
common mode range is extended from V
reversal.
4.3 Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: 150 mV maximum above
and below the rail when connected to a 2 kΩ resistive load to
- 0.2 V to V

4.4 Input offset voltage drift over temperature
The maximum input voltage drift over temperature variation is defined as follows:
for T
min < T < Tmax.

-----------------------------------------------------
T25° C–
4.5 PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
4.6 Macromodel
Accurate macromodels of the LMV82x are available on STMicroelectronics’ web site at
www.st.com. This model is a trade-off between accuracy and complexity (that is, time
simulation) of the LMV82x operational amplifiers. It emulates the nominal performances of a
typical device within the specified operating conditions mentioned in the datasheet. It also
helps to validate a design approach and to select the right operational amplifier, but it does
not replace on-board measurements.
