Pin Assignment

General Description

The AP393 consists of two independent precision

voltage

comparators

with

an

offset

voltage

specification as low as 2.0 mV 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.

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.
