Features Low supply current: 85µA (typ) Low offset voltage: 2mV (typ) Low input bias current: 2nA (typ) Input common mode to GND Interfaces to CMOS logic Wide supply range: 3V < V+ < 32V Small Outline Package available Pin-for-pin compatible with LM324 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 applications. These amplifiers are ideal in applications which include portable instrumentation, battery backup equipment, and other circuits which require good DC performance and low supply current.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
