Low-power single voltage comparator

STMicroelectronics 

TS391, TS391A

Low-power single voltage comparator

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 (0.2 mA)

independent of supply voltage

(1 mW/comparator at 5 V)

Low input bias current: 25 nA typ.

Low input offset current: ±5 nA typ.

Low input offset voltage: ±2 mV max. for

TS391A

Input common-mode voltage range includes

ground

Low output saturation voltage: 250 mV typ.

(Io= 4 mA)

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.
