Overview
The TS3702CDT, produced by STMicroelectronics, is a micropower CMOS dual voltage comparator. It is characterized by its extremely low power consumption of 9µA typical per comparator, which is 20 times less than the bipolar LM393. This component features a push-pull CMOS output stage, eliminating the need for an external pull-up resistor, thus saving power and space. The TS3702CDT maintains response times similar to the LM393 despite its low power consumption.
