DESCRIPTION
The UTC TS391/A/B consist 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 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 to
* +34V or ± 1V to ± 18V
* Very low supply current (0.2mA) independent of supply voltage (1 mW /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.(Io=4mA).
* Differential input voltage range equal to the supply voltage.
