LM2901VQDR TI Comparator | 14-SOIC | Quad, Low Power, 2V to 36V

Product Overview

The LM2901VQDR from Texas Instruments is a quad differential comparator designed for low-power, wide-supply-voltage applications. Housed in a compact 14-SOIC package, it offers four independent comparators with open-collector outputs, making it ideal for interfacing with various logic families. The device operates from a single supply of 2V to 36V or dual supplies of ±1V to ±18V, with low supply current drain (0.4 mA per comparator at 5V). It features a common-mode input voltage range that includes ground, making it suitable for single-supply systems.
