Product Summary

The LM2901M is a low power low offset voltage quad comparator with an offset voltage specification as low as 2 mV max for all four comparators. The LM2901M is 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. These comparators 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, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM2901M was designed to directly interface with TTL and CMOS.
