DESCRIPTION

This device consists of two independent low power 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.

■ 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

■ 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
