Application information

4.1

Operating voltages

The LMV321L, LMV358L, and LMV324L can operate from 2.7 to 5.5 V. The devices’

parameters are fully specified for 2.7 V and 5 V power supplies. Additionally, the main

specifications are guaranteed in extended temperature ranges from -40 ° C to +125 ° C.

4.2

Input common-mode range

The LMV321L, LMV358L, and LMV324L have an input common-mode range that includes

output phase reversal.

4.3

Rail-to-rail output

The operational amplifiers’ output levels can go close to the rails: 180 mV maximum above

and below the rail when connected to a 10 k

4.4

Input offset voltage drift over temperature

The maximum input voltage drift over the temperature variation is defined as follows.

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 LMV321L, LMV358L, and LMV324L 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 LMV321L, LMV358L, and LMV324L

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.
