LM2903BIDR TI Comparator | 8-SOIC | Dual, Low Power, 2V-36V

Product Overview

The LM2903BIDR is a dual differential comparator from Texas Instruments, designed for low-power and wide supply voltage range applications. It operates from a single supply of 2V to 36V or dual supplies of ±1V to ±18V, making it versatile for various industrial and automotive systems. The device features low supply current (0.4 mA per comparator), open-collector outputs for wired-OR configurations, and a common-mode input voltage range that includes ground. Housed in an 8-SOIC package, the LM2903BIDR is ideal for space-constrained designs.
