LM111-LM211-LM311

Voltage Comparators

■ Maximum input current: 150nA

■ Maximum offset current: 20nA

■ Differential input voltage range: ±30V

■ Power consumption:135mW at ±15V

■ Supply voltage: +5V to ±15V

■ Output current: 50mA

Description

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 outputs currents as high as 50mA.
