Overview
The LM339DRG4, produced by Texas Instruments, is a quad differential comparator that belongs to the next generation of the industry-standard LM339 and LM2901 comparator family. These B-version comparators offer significant improvements over their predecessors, including lower offset voltage, higher supply voltage capability, lower supply current, and lower input bias current. The LM339B devices are designed to operate from a single power supply over a wide range of voltages and are compatible with TTL, MOS, and CMOS outputs.
