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.
The LMV358 is available in the MSOP-8 and SO-8 packages.
