The LMV324 and LMV358 are low-voltage (2.7 V
to 5.5 V) versions of the dual and quad operational
amplifiers, LM324 and LM358, that operate from
5 V to 30 V. The LMV321 is the single-amplifier
version.

The LMV321, LMV324, and LMV358 are the most
cost-effective solutions for applications where
low-voltage operation, space saving, and low
price are needed. They offer specifications that
meet or exceed those of the familiar LM358 and
LM324 devices. These devices have rail-to-rail

capability,
and
the
input
common-mode voltage range includes ground.
They all exhibit excellent speed-to-power ratios,
achieving 1MHz of bandwidth at 1-V/µs slew rate
with low supply current.
The LMV321 is available in the ultra-small DCK package, which is approximately one-half the size of the DBV
package. This package saves space on printed circuit boards and enables the design of small portable
electronic devices. It also allows the designer to place the device closer to the signal source to reduce noise
pickup and increase signal integrity.
The LMV321I, LMV324I, and LMV358I devices are characterized for operation from –40°C to 85°C.
