TS391

Low-power single voltage comparator

Datasheet − production data

Features

■ Wide single supply voltage range or dual

supplies +2 V to +36 V or

±1V to ±18 V

■ Very low supply current (0.2 mA) independent

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

■ Low input bias current: 25 nA typ.

■ Low input offset current: ±5nA typ.

■ Low input offset voltage: ±1mV typ.

■ Input common-mode voltage range includes

ground

■ Low output saturation voltage: 250 mV typ.

=4mA)

■ Differential input voltage range equal to the

supply voltage

■ TTL, DTL, ECL, CMOS compatible outputs

Description

This device consists of a low-power voltage

comparator designed specifically to operate from

a single supply over a wide range of voltages.

Operation from split power supplies is also

possible.

This comparator also has a unique characteristic

in that the input common-mode voltage range

includes ground, even though operated from a

single power supply voltage.
