LP324/LP2902

Micropower Quad Operational Amplifier

General Description

The LP324 series consists of four independent, high gain

internally compensated micropower operational amplifiers.

These amplifiers are specially suited for operation in battery

systems while maintaining good input specifications, and

extremely low supply current drain. In addition, the LP324

has an input common mode range, and output source range

which includes ground, making it ideal in single supply ap-

plications.

These amplifiers are ideal in applications which include por-

table instrumentation, battery backup equipment, and other

circuits which require good DC performance and low supply

current.
