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.
