LOW POWER SINGLE VOLTAGE COMPARATORS

.WIDE SINGLE SUPPLY VOLTAGE RANGE OR

DUAL SUPPLIES +2V TO +36V OR ±1V TO

.±18V

VERY LOW SUPPLY CURRENT (0.2mA) INDEPENDENT OF SUPPLY VOLTAGE

.(1 mW/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 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 eventhough operatedfrom a single power supply voltage.
