LM2903QDRQ1 TI Comparator | 8-SOIC | Dual, Low Power, 2V-36V

Product Overview

The LM2903QDRQ1 is a dual differential comparator from Texas Instruments, designed for automotive and industrial applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or dual supplies ±1V to ±18V) and features low supply current (0.4 mA per comparator). The device is qualified to AEC-Q100 for automotive use and is available in an 8-pin SOIC package.
