  • 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
