LM2903AVQDRG4Q1 TI Comparator | 8-SOIC | Dual, Low Power, Automotive Grade

Product Overview

The LM2903AVQDRG4Q1 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 2 V to 36 V (or ±1 V to ±18 V for dual supplies) and features low supply current drain (0.4 mA per comparator at 5 V). The device is qualified to AEC-Q100 standards for automotive applications and is available in an 8-pin SOIC package. It offers open-collector outputs that can be connected to achieve wired-AND logic, making it versatile for various system designs.
