LM393DRG3 TI Low-Power Dual Comparator | 8-SOIC | 2mV Offset, 0.4μA

Product Overview

The LM393DRG3 from Texas Instruments is a low-power, low-offset voltage dual comparator designed for industrial and automotive applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies) and features extremely low supply current drain (0.4mA per comparator) independent of supply voltage. The open-collector outputs allow wired-AND connections and interface with various logic families. Housed in an 8-SOIC package, this device is ideal for space-constrained designs requiring precision and reliability.
