LM211   Product is in volume production.

Voltage comparator with strobe

Download Datasheet

The LM111, LM211, LM311 are voltage comparators that have low input currents.

They are also designed to operate over a wide range of supply voltages: from standard ±15V operational amplifier 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 and can switch voltages up to +50V at output currents as high as 50mA.

Key Features

  • Output current: 50mA
  • Maximum input current: 150nA
  • Differential input voltage range: ±30V
  • Maximum offset current: 20nA
  • Supply voltage: +5V to ±15V
  • Power consumption:135mW at ±15V
