LM111/LM211/LM311

Voltage Comparator

1.0 General Description

The LM111, LM211 and LM311 are voltage comparators that

have input currents nearly a thousand times lower than

devices like the LM106 or LM710. They are also designed to

operate 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 mA.

the devices are also much less prone to spurious oscilla-

tions. The LM111 has the same pin configuration as the

LM106 and LM710.

The LM211 is identical to the LM111, except that its perfor-

mance is specified over a −25˚C to +85˚C temperature range

instead of −55˚C to +125˚C. The LM311 has a temperature

range of 0˚C to +70˚C.

2.0 Features

n Operates from single 5V supply

n Input current: 150 nA max. over temperature

n Offset current: 20 nA max. over temperature

n Differential input voltage range: 30V

n Power consumption: 135 mW at 15V

Both the inputs and the outputs of the LM111, LM211 or the

LM311 can be isolated from system ground, and the output

can drive loads referred to ground, the positive supply or the

negative supply. Offset balancing and strobe capability are

provided and outputs can be wire OR’ed. Although slower

than the LM106 and LM710 (200 ns response time vs 40 ns)

3.0 Typical Applications (Note 3)

Offset Balancing

Strobing

00570437

Note: Do Not Ground Strobe Pin. Output is turned off when current is

pulled from Strobe Pin.

Increasing Input Stage Current (Note 1)

Detector for Magnetic Transducer

00570438

Note 1: Increases typical common mode slew from 7.0V/µs to 18V/µs.
