The AP331A is a precision voltage comparators with an offset voltage specification as low as 8.0 mV max for comparator 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 comparator also have a unique characteristic in that 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 AP331A is designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the AP331A will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
