LM311B - Voltage comparator

General Description

The LM111 series are voltage comparators that have input currents approximately a hundred times lower than devices like the µA710.

They are designed to operate over a wider range of supply voltages; from standard ±15V op amp supplies down to a single 3V supply.

Key Features

  • Operates from single 3V supply (LM311B).
  • Maximum input bias current: 150nA (LM311.
  • 250nA).
  • Maximum offset current: 20nA (LM311.
  • 50nA).
  • Differential input voltage range: ±30V.
  • Power consumption: 135mW at ±15V.
  • High sensitivity.
  • 200V/mV.
  • Zero crossing detector.

Philips Semiconductors Linear Products Product specification Voltage comparator LM111/211/311/ LM311B DESCRIPTION The LM111 series are voltage comparators that have input currents approximately a hundred times lower than devices like the µA710. They are designed to operate over a wider range of supply voltages; from standard ±15V op amp supplies down to a single 3V supply. 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 50mA. Both the inputs and the outputs of the LM111 series can be isolated from system ground, and the output can drive loads referred to ground, the positive supply, or the negative supply.
