LM193DR TI Comparator | 8-SOIC | Low Power, Dual Channel

Product Overview

The LM193DR from Texas Instruments is a dual-channel, low-power voltage comparator designed for a wide range of applications. It operates from a single power supply over a wide voltage range of 2.0V to 36V (or ±1.0V to ±18V for dual supplies) and features low supply current drain (0.4 mA per comparator at 5V). The device is offered in an 8-pin SOIC package, making it suitable for space-constrained designs. With open-collector outputs, the LM193DR can be used in wired-OR configurations and can drive loads up to 20 mA. Its low offset voltage (2 mV typical) and fast response time (1.3 μs) make it ideal for precision threshold detection and signal conditioning.
