November 2005 Revision 5 1/13

■ Wide single supply voltage range or dual

supplies : +2V to +36V or ±1V to ±18V

■ Very low supply current (0.4mA)

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.

(Io = 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.
