LM3302DRG4 TI Comparator | 14-SOIC | Quad, Low Power, 0.3μA

Product Overview

The LM3302DRG4 is a quad low-power voltage comparator from Texas Instruments, designed for applications requiring low supply current and wide supply voltage range. It features open-collector outputs, making it suitable for driving loads referenced to a positive supply. The device operates from a single supply of 2V to 28V or dual supplies of ±1V to ±14V. With a typical supply current of only 0.3μA per comparator, it is ideal for battery-powered systems.
