GENERAL DESCRIPTION
The SX8661Z is an ultra low power, fully integrated 8-channel solution for capacitive touch-button and proximity detection applications. Unlike many capacitive touch solutions, the SX8661Z features dedicated capacitive sense inputs (that requires no external components) in addition to 8 general purpose I/O ports (GPIO). Each of the 8 on-chip GPIO/LED driver is equipped with independent PWM source for enhanced visual effect such as dimming, and breathing.
The SX8661Z includes a capacitive 10 bit ADC analog interface with automatic compensation up to 100pF.
