LM393PSR TI Low-Power Dual Comparator | 8-SO | 2mV Offset, 0.4μA

Product Overview

The LM393PSR from Texas Instruments is a low-power, dual-channel voltage comparator designed for applications requiring high precision and low current consumption. Housed in an 8-pin SO package, this device operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies). It features a typical input offset voltage of 2mV and a low supply current of 0.4mA per comparator, making it ideal for battery-powered and portable electronics. The LM393PSR offers open-collector outputs that can be connected to various logic levels, providing flexibility in system design.
