NJM2903C

NJM2903C
SINGLE-SUPPLY DUAL COMPARATOR
■ GENERAL DESCRIPTION
The NJM2903C consist of two independent voltage comparators that are
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.
The NJM2903C has a unique characteristic: 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, square-wave and time delay generators; wide range VCO ; MOS clock
timers; multivibrators and high voltage digital logic gates. The NJM2903C were
designed to directly interface with TTL and MOS. When operated from both plus
and minus power supplies, the NJM2903C will directly interface with MOS logic
where their low power drain is a distinct advantage over standard comparators.
