Product Overview
The LM339DRG3 from Texas Instruments is a quad differential comparator designed for low-power, low-voltage applications. It operates from a single power supply over a wide voltage range of 2V to 30V, or dual supplies of ±1V to ±15V. The device features low supply current (0.8 mA typical) and open-collector outputs that allow wired-AND connections. Housed in a 14-pin SOIC package, it is ideal for space-constrained designs.
