NJM2903/2403
SINGLE-SUPPLY DUAL COMPARATOR
■ GENERAL DESCRIPTION
The NJM2903/2403 consist of two independent precision voltage
comparators with an offset voltage specification as low as 5.0mV 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. The
NJM2903/2403 have 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 NJM2903/2403 were designed to directly
interface with TTL and MOS. When operated from both plus and minus
power supplies, the NJM2903/2403 will directly interface with MOS logic
where their low power drain is a distinct advantage over standard
comparators.
