LMV321/LMV358/LMV324
GENERAL PURPOSE, LOW VOLTAGE, RAIL-TO-RAIL
OUTPUT OPERATIONAL AMPLIFIERS
Description
NEW PRODUCT
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.
