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.
