Overview
The LM339PWR, produced by Texas Instruments, is a quad differential comparator integrated circuit. It is part of the next-generation B-version of the industry-standard LM339 and LM2901 comparator family. These devices are designed to offer improved specifications, including lower offset voltage, higher supply voltage capability, lower supply current, and enhanced ESD performance. The LM339B and LM2901B can drop-in replace earlier versions (A and V grades) of the LM239, LM339, and LM2901 comparators. Each device consists of four independent voltage comparators that can operate from a single power supply over a wide range of voltages.
