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 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 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.
