CT8233LQK is a single channel capacitive touch detection chip used to replace traditional mechanical switches. Manufactured using CMOS technology, with built-in voltage stabilization modules, hardware jitter reduction, and environmental value adaptive algorithms, various effective measures are integrated to greatly improve its anti-interference performance. It can achieve touch function with isolation protection of media (plastic shell, glass ceramic, acrylic, etc.), with high safety. With wide operating voltage characteristics, it can be configured into multiple operating modes through external pins, and is widely used in DC consumer electronics such as TWS, educational toys, light control, etc.
