DESCRIPTION
These devices consist of four independentprecision
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 though operated from a single
power supply voltage.
