Overview

The LM339DT is a low-power quad Precision-Voltage Comparator with an offset voltage specification as low as 2mV maximum. The comparator has been designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. This comparator also has unique characteristic in that the input common mode voltage range includes ground even though operated from a single power supply voltage.
