Low power dual voltage comparators

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.

■ Low input offset voltage: ±1 mV typ.

■ Input common-mode voltage range includes

ground

■ Low output saturation voltage: 250 mV typ.

=4mA)

■ Differential input voltage range equal to the

supply voltage

■ TTL, DTL, ECL, MOS, CMOS compatible

outputs

Description

These devices consist of two independent low

voltage comparators designed specifically to

operate from a single supply over a wide range of

voltages. Operation from split power supplies is

also possible.

These comparators also have a unique

characteristic in that the input common-mode

voltage range includes ground even though

operated from a single power supply voltage.
