Overview
The TLC3702MDRG4, produced by Texas Instruments, is a dual micropower voltage comparator integrated circuit. It is designed to operate from a single supply and is compatible with modern HCMOS logic systems. The TLC3702 is functionally similar to the LM339 but consumes one-twentieth of the power while maintaining similar response times. This component utilizes Texas Instruments' LinCMOS™ process, which offers superior analog performance, low power consumption, high input impedance, and low bias currents. The LinCMOS™ process also ensures extremely stable input offset voltages, making it ideal for building reliable CMOS comparators.
