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-Vshdn must not exceed 6 V, Vin must not exceed 6 V.
6. Short-circuits can cause excessive heating and destructive dissipation.
7. Rth are typical values.
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
4.1
Operating voltages
The LMV82x and LMV82xA 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 and LMV82xA devices have an input common mode range that includes
ground. The input common mode range is extended from V - 0.2 V to V - 1 V, with no
cc-
cc+
output phase reversal.
4.3
4.4
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 Vcc/2.
Input offset voltage drift over temperature
The maximum input voltage drift over temperature variation is defined in Equation 1.
Equation 1
ΔVio
Vio(T) – Vio(25° C)
-----------------------------------------------------
T – 25° C
------------ = max
ΔT
for Tmin < T < Tmax.
4.5
4.6
PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
Macromodel
Accurate macromodels of the LMV82x and LMV82xA are available on STMicroelectronics’
web site at www.st.com. These models are a trade-off between accuracy and complexity
(that is, time simulation) of the LMV82x and LMV82xA operational amplifiers. They emulate
the nominal performances of a typical device within the specified operating conditions
mentioned in the datasheet. They also help to validate a design approach and to select the
right operational amplifier, but they do not replace on-board measurements.

Shutdown function
The operational amplifier is enabled when the SHDN pin is pulled high. To disable the
amplifier, the SHDN pin must be pulled down to V . When in shutdown mode, the
CC-
amplifier output is in a high impedance state. The SHDN pin must never be left floating but
tied to V
or V
.

The turn-on and turn-off times are calculated for an output variation of ±200 mV. Figure 21
and Figure 22 show the test configurations. Figure 23 and Figure 24 show the respective
results with these test configurations.
