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.

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
