LMV321/ 324/ 358
GENERAL PURPOSE, LOW VOLTAGE,
RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIERS
Description
The LMV321/LMV358/LMV324 are low voltage (2.7V to 5.5V) single,
dual and quad operational amplifiers. The LMV321/LMV358/LMV324
are designed to effectively reduce cost and space at low voltage
levels.
These devices have the capability of rail-to-rail output swing and input
common-mode voltage range includes ground. They can also achieve
an efficient speed-to-power ratio, utilizing 1 MHz bandwidth and
1V/µs slew rate at a low supply current. Reducing noise pickup and
increasing signal integrity can be achieved by placing the device
close to the signal source.
The LMV321 is available in 5-Pin SOT353/SOT25 packages that
reduce space on PC boards and portable electronic devices. The
LMV324 is available in the
SO-14 and TSSOP-14 package.

4. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the
device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the
Electrical Characteristics.
5. Shorting output to V+ will adversely affect reliability.
6. Shorting output to V- will adversely affect reliability.
