Description

The LM311N is a voltage comparator that has input currents nearly a thousand times lower than devices like the LM106 or LM710. It also operates over a wider range of supply voltages: from standard ±15V op amp supplies down to the single 5V supply used for IC logic. Their output is compatible with RTL, DTL, and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50 m.

Applications include a level detector for battery-powered applications, a low-power lamp or relay driver, and a low-power zero-crossing detector.

Features

  • Low power drain, 900 mW on 5V supply
  • Emitter output can swing below negative supply
  • Operates from ±15V or a single supply as low as 3V
