LM193, LM293, LM393

Low power dual voltage comparators

Datasheet − production data

Features

■ Wide single-supply voltage range or dual

supplies: +2 V to +36 V or ±1 V to ±18 V

■ Very low supply current (0.45 mA) independent

of supply voltage (1 mW/comparator at +5 V)

■ Low input bias current: 20 nA typ.

■ Low input offset current: ±3 nA typ.

■ Low input offset voltage: ±1 mV typ.

■ Input common-mode voltage range includes

ground

■ Low output saturation voltage: 80 mV typ.

sink

=4mA)

■ Differential input voltage range equal to the

supply voltage

■ TTL, DTL, ECL, MOS, CMOS compatible

outputs

■ Available in DIP8, SO-8, TSSOP8, MiniSO-8,

and DFN8 2 x 2 mm packages

Description

The LM193, LM293, and LM393 devices consist

of two independent low voltage comparators

designed specifically to operate from a single

supply over a wide range of voltages. Operation

from split power supplies is also possible.

These comparators also have a unique

characteristic in that the input common-mode

voltage range includes ground even though

operated from a single power supply voltage.
