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
DE SC RI P TI O N
These devices consist of a low power voltage com-
parator designed specifically to operate from a sin-
gle 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.
