LM2903Q2T ST Comparator | 8-DFN(2x2) | Dual, Low Power, 2V-36V

Product Overview

The LM2903Q2T is a dual low-power voltage comparator from STMicroelectronics, 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 (0.4mA per comparator). The device is offered in a compact 8-DFN (2x2mm) package, making it suitable for space-constrained designs. It provides open-collector outputs that can be connected to various logic levels, and its input common-mode voltage range includes ground, even when operating from a single supply.
