LM2903AVQPWR TI Comparator | 8-TSSOP | Dual, 2V to 36V, Low Offset

Product Overview

The LM2903AVQPWR is a dual differential comparator from Texas Instruments, designed for industrial and automotive applications. It operates from a single power supply over a wide voltage range of 2V to 36V, or dual supplies of ±1V to ±18V. The device features low input offset voltage (typically 2mV) and low supply current (0.4mA per comparator), making it suitable for battery-powered systems. The open-collector outputs allow wired-AND connections and interface with various logic families. Housed in a compact 8-TSSOP package, it is ideal for space-constrained designs.
