Product Summary
The LM2901DR consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. The LM2901DR 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. The comparator also has 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 LM2901DR was designed to directly interface with TTL and CMOS.
