LP311P TI Comparator | 8-PDIP | Single, Open-Collector, Low Power

Product Overview

The LP311P from Texas Instruments is a low-power, single-channel voltage comparator designed for general-purpose applications. It features an open-collector output, making it suitable for driving loads up to 50V and 50mA. The device operates from a single supply voltage ranging from 3V to 30V or dual supplies of ±1.5V to ±15V. With a typical supply current of only 0.4mA, it is ideal for battery-powered systems. The LP311P is housed in an 8-pin PDIP package, offering ease of integration into through-hole PCB designs.
