Datasheet - production data
Description
The LMV321L, LMV358L, and LMV324L are
single, dual and quad operational amplifiers with
rail-to-rail output capabilities. They are specifically
designed to operate at low voltages (2.7 V to 5 V)
with enhanced performances compared to the
industry standard LM3xx series.
The LMV321L, LMV358L, and LMV324L are
offered in tiny packages, allowing the devices to
be used in small portable electronic applications
and to be placed closer to the actual signal.
The LMV321L, LMV358L, and LMV324L are
complete cost-effective solutions for application
designs where cost is of primary importance.

information
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
ground. The input common-mode range is extended from VCC- - 0.2 V to VCC+ - 1 V, with no
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 kΩ resistive load to VCC/2.
4.4 Input offset voltage drift over temperature
The maximum input voltage drift over the temperature variation is defined as follows.
Δ---Δ--V--T--i--o- = ma x V---io---(--)T-T--2-––--V--5-i-o-°--(C-)2-5---°---C----
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 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.
