4 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
cc-
- 0.2 V to V
cc+
- 1 V, with no
output phase 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 V
cc
/2.
4.4 Input offset voltage drift over temperature
The maximum input voltage drift over temperature variation is defined in Equation 1.
Equation 1
for Tmin < T < Tmax.
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 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.
