SINGLE-SUPPLY QUAD COMPARATOR
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
These devices offer higher frequency operation and faster
switching than can be had from internally compensated quad op
amps.Indeed for single-supply applications,the Darlington PNP
input stage allows them to compare voltages that include
ground.The two-stage common-emitter output circuit provides
gain and output sink capacity of 6mA at an output level of
400mV.The output collector is left open,permitting the designer
to drive devices in the range of 2V to 36V.
■ FEATURES
● Operating Voltage ( +2V~+36V )
