Micropower Quad Operational Amplifier - LP324-N


Micropower Quad Operational Amplifier

Recommended alternative parts

  • LPV324-N  -  Lower Power, Lower Voltage Version


The LP324-N 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-N 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.


  • Low Supply Current: 85μA (typ)
  • Low Offset Voltage: 2mV (typ)
  • Low Input Bias Current: 2nA (typ)
  • Input Vommon Mode to GND
  • Interfaces to CMOS Logic
  • Wide Supply Range: 3V < V+ < 32V
  • Small Outline Package Available
  • Pin-for-pin Compatible with LM324
