SX8644 - Capacitive Button and Slider Touch Controller
SEMTECH
General Description
The SX8644 is an ultra low power, fully integrated 12-channel solution for capacitive touch-buttons and slider applications.
Key Features
dedicated capacitive sense inputs (that requires no external components) in addition to 8 general purpose I/O ports (GPIO). Each GPIO is typically configured as LED driver with independent PWM source for enhanced lighting control such as intensity and fading. The SX8644 includes a capacitive 10 bit ADC analog interface with automatic compensation up to 100pF. The high resolution capacitive sensing supports a wide variety of touch pad sizes and shapes and allows capacitive buttons to be created u.
