LM2901DRG3 TI Comparator | 14-SOIC | Quad, Low Power, 2V to 36V

Product Overview

The LM2901DRG3 is a quad differential comparator from Texas Instruments, designed for low-power and wide supply voltage range 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 independent of supply voltage. Its common-mode input voltage range includes ground, enabling direct sensing near ground. The LM2901DRG3 is characterized for operation from -40°C to +125°C, suitable for industrial and automotive environments.
