General Description

The NJM2903 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 has 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 was designed to directly interface with TTL and MOS. When operated from both plus and minus power supplies, the NJM2903 will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
