LP311PS TI Low-Power Comparator | 8-SO | Single Supply, Open Collector

Product Overview

The LP311PS from Texas Instruments is a low-power, single-supply voltage comparator designed for applications requiring minimal power consumption. It features an open-collector output, making it suitable for driving loads up to 50V. The device operates from a single supply voltage range of 3V to 36V or dual supplies of ±1.5V to ±18V. With a typical supply current of just 300 µA, it is ideal for battery-powered and portable equipment. The LP311PS is offered in an 8-pin SOIC package (8-SO) and is specified for the industrial temperature range of -40°C to +85°C.
