LM393PW TI Low-Power Dual Comparator | 8-TSSOP | 2mV Offset, 0.3μA

Product Overview

The LM393PW from Texas Instruments is a low-power, dual-channel voltage comparator designed for industrial and automotive applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies) and features low supply current (0.4mA typical per comparator). The open-collector output allows wired-AND connection and interface with various logic families. Housed in a compact 8-TSSOP package, it is ideal for space-constrained designs.
