SX863 Capacitive Touch Controller

Semtech SX863 Capacitive Touch Controller is a fully-integrated 8-channel solution for capacitive touch buttons and sliders in proximity detection applications with up to 10cm of proximity detection. THE SX863 features dedicated capacitive sense inputs in addition to eight general-purpose I/O ports (GPIO). Each GPIO is typically configured as an LED driver with an independent PWM source for enhanced lighting control such as intensity and fading. The SX8638 includes a capacitive 10-bit ADC analog interface with automatic compensation of up to 100pF. The high-resolution capacitive sensing supports a wide variety of touchpad sizes/shapes. It allows capacitive buttons to be created using thick overlay materials (up to 5mm) for a highly robust and ESD immune system design.
