General Description
The NJM2903C / NJM2903CA 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 / NJM2903CA 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 / NJM2903CA were designed to directly interface with TTL and MOS. When operated from both plus and minus power supplies, the NJM2903C / NJM2903CA will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
