Product Overview
The TLC3702MDR from Texas Instruments is a dual, low-power, high-speed voltage comparator fabricated using LinCMOS technology. It features push-pull outputs, eliminating the need for an external pull-up resistor, and operates from a single supply voltage of 2.5V to 16V or dual supplies of ±1.25V to ±8V. With a typical response time of 2.5 microseconds and low supply current of 150 µA per comparator, it is ideal for battery-powered and portable applications. The device is offered in an 8-pin SOIC package and is specified for the industrial temperature range of -40°C to 85°C.
