AP393A
LOW POWER LOW OFFSET VOLTAGE DUAL
COMPARATORS
General Description
Features
The AP393A consists of two independent precision voltage
comparators with an offset voltage specification as low as
8.0mV max for two comparators which were designed specifically
to operate from a single power supply over a wide range of
voltages. Operation from split power supplies is also possible and
the low power supply current drain is independent of the
magnitude of the power supply voltage. 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 supply
Voltage range: 2.0V to 36V
Single or dual supplies: ±1.0V to ±18V
Very low supply current drain (0.4mA) – independent of
supply voltage
Low input biasing current: 150nA
Low input offset current: ±70nA
Low input offset voltage: ±4mV

Input common-mode voltage range includes ground
Differential input voltage range equal to the power
supply voltage
Application areas include limit comparators, simple analog to
digital converters; pulse, square wave and time delay generators;
wide range VCO; MOS clock timers; multivibrators and high
voltage digital logic gates. The AP393A is designed to directly
interface with TTL and CMOS. When operated from both plus
and minus power supplies, the AP393A will directly interface with
MOS logic where their low power drain is a distinct advantage
over standard comparators.
