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.
