LP2902/LP324

Micropower Quad Operational Amplifier

General Description

The LP324 series consists of four independent, high gain in-

ternally compensated micropower operational amplifiers.

These amplifiers are specially suited for operation in battery

systems while maintaining good input specifications, and ex-

tremely 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 appli-

cations.

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.
