DESCRIPTION

The UTC TS391/A/B/C 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.

FEATURES

* Wide single supply voltage range or dual supplies +2V~+36V or ±1V~±18V

* Very low supply current (0.2mA) independent of supply voltage (1mW /comparator at +5V)

* Low input bias current: 25nA typ.

* Low input offset current: ±5nA typ.

* Low input offset voltage: ±1mV typ

* Input common-mode voltage range includes ground.

* Low output saturation voltage: 250mV typ.(IOUT=4mA).

* Differential input voltage range equal to the supply voltage.

* TTL, DTL, ECL, CMOS Compatible outputs.
