This device consists of four independent precision voltage comparators with an offset voltage specification as low as 2mV max for CM339. All these comparators were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. 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. !
