LP311DR TI Comparator | 8-SOIC | Single, Open-Collector, Low Power

Product Overview

The LP311DR from Texas Instruments is a low-power, single-channel voltage comparator designed for applications requiring high precision and low supply current. It features an open-collector output, making it suitable for interfacing with various logic families. The device operates from a single supply voltage as low as 3.0V up to 36V, or dual supplies of ±1.5V to ±18V. Housed in an 8-pin SOIC package, the LP311DR offers a compact solution for space-constrained designs.
