Description
The CD2901 consists of four independent precision voltage comparators with an offset voltage specification as low as 5.0 mV max for four comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Application areas include limit comparators, simple analog to digital converters，pulse, square wave, Zero crossing detector (single power supply) and time delay generators.
