LM393N/NOPB .

The LM393N/NOPB is a low power low offset voltage Dual Comparator with an offset voltage specification as low as 2mV maximum 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. This comparator has a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. The LM193-N series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, this comparator will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
