LM393ADE4 TI Comparator | 8-SOIC | Dual, Low Power, 2V to 36V

Product Overview

The LM393ADE4 from Texas Instruments is a dual differential comparator designed for low-power applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or dual supplies ±1V to ±18V) and features low supply current drain (0.4 mA typical) independent of supply voltage. The device has open-collector outputs that can be connected to other open-collector outputs to achieve wired-AND logic. The LM393ADE4 is offered in the industry-standard 8-pin SOIC package, making it suitable for space-constrained designs.
