General Description

This device consists of two independent lowpower voltage comparators designed specifically to operate from a single supply over a wide range of voltages.

Operation from split power supplies is also possible.

In addition, the device has a unique characteristic in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.

Key Features

Wide single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V.
Very low supply current (0.4 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.
Input common-mode voltage range includes negative rail.
Low output saturation voltage: 250 mV typ. (IO = 4 mA).
Differential input voltage range equal to the supply voltage.
TTL, DT.
