LMV321/LMV358/LMV324
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 1 V/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
SOP-14L and
TSSOP-14L package.
The LMV358 is available in the MSOP-8L and SOP-8L
packages.

2. 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.
3. Shorting output to V+ will adversely affect reliability.
4. Shorting output to V- will adversely affect reliability.
