Product Summary
The LM339DT is a lowpower quad voltage comparator which consists of four independent precision voltage comparators with an offset voltage specifications as low as 2mV max for LM339A, LM239A and LM139A. The comparator was designed specifically to operate from a single power supply aver a wide range of voltages. Operation from split power supplies is also possible. The LM339DT also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.
