GSL3680 PDF – Capacitive Touchscreen Controller ( Datasheet )

A capacitive touchscreen controller is an integrated circuit (IC) that is responsible for detecting and processing touch inputs on a capacitive touchscreen panel. Capacitive touchscreens are widely used in smartphones, tablets, laptops, interactive kiosks, and various other electronic devices due to their responsiveness, durability, and multi-touch capabilities. The controller plays a crucial role in accurately sensing touch gestures and translating them into digital signals that the device’s operating system can understand and respond to.
