LM393DRE4 TI Low-Power Dual Comparator | 8-SOIC | 2mV Offset, 0.3μA

Product Overview

The LM393DRE4 from Texas Instruments is a low-power, low-offset voltage dual comparator designed for applications requiring high precision and minimal power consumption. Housed in an 8-SOIC 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 open-collector outputs that can be connected to various voltage levels, making it versatile for interfacing with different logic families. The LM393DRE4 is characterized for operation from 0°C to 70°C and is ideal for battery-powered systems, industrial controls, and signal conditioning.
