LM2903VQPWRQ1 TI Comparator | 8-TSSOP | Dual, Low Power, 2V-36V

Product Overview

The LM2903VQPWRQ1 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 drain (0.4 mA typical per comparator) independent of supply voltage. The device has open-collector outputs that can be connected to achieve wired-AND logic. It is offered in a compact 8-TSSOP package, making it suitable for space-constrained designs.
