LP311DG4 TI Comparator | 8-SOIC | Single, Open-Collector Output

Product Overview

The LP311DG4 is a low-power, single-channel voltage comparator from Texas Instruments, designed for applications requiring precision and low supply current. It features an open-collector output stage, making it suitable for interfacing with various logic families and driving loads such as relays and LEDs. The device operates from a single supply voltage as low as 3V up to 30V, or dual supplies of ±1.5V to ±15V. Its low offset voltage and high input impedance ensure accurate comparisons in battery-powered and industrial systems.
