DESCRIPTION These devices consist of fourindependentprecision voltage comparators with an offset voltage specifications as low as 2mV max for LM339A, LM239A and LM139A. 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 thoughoperatedfrom a single power supply voltage. PIN CONNECTIONS (top view)
