LM2903BHQDRQ1 TI Comparator | 8-SOIC | Dual, Low Power, Automotive Grade

Product Overview

The LM2903BHQDRQ1 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 (0.4 mA per comparator at 5 V). The device is qualified to AEC-Q100 (Grade 1) and is available in an 8-pin SOIC package. It offers open-collector outputs, allowing wired-AND connections, and has a typical response time of 1.3 μs. The LM2903BHQDRQ1 is a direct upgrade to the LM2903 series with improved performance and reliability.
