AP393
LOW POWER LOW OFFSET VOLTAGE DUAL
COMPARATORS
General Description
Features
The AP393 consists of two independent precision voltage
comparators with an offset voltage specification as low as 2.0mV
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: 25nA
Low input offset current: ±5nA
Maximum offset voltage: ±3mV
•
•
•
•
•
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, squarewave and time delay generators;
wide range VCO; MOS clock timers; multivibrators and high
voltage digital logic gates. The AP393 is designed to directly
interface with TTL and CMOS. When operated from both plus
and minus power supplies, the AP393 will directly interface with
MOS logic where their low power drain is a distinct advantage
over standard comparators.

Low output saturation voltage: 250mV at 4mA
Output voltage compatible with TTL, DTL, ECL, MOS
and CMOS logic systems
