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.
