SX8661
SX8661 is Capacitive Button Touch and Proximity Controller manufactured by SEMTECH.
Low Power, Capacitive Button Touch and Proximity Controller (8 sensors) with LED Drivers and Analog Output
ADVANCED MUNICATIONS & SENSING
GENERAL DESCRIPTION
The SX8661 is an ultra low power, fully integrated 8channel solution for capacitive touch-button and proximity detection applications. Unlike many capacitive touch solutions, the SX8661 Features dedicated capacitive sense inputs (that requires no external ponents) 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 SX8661 includes a capacitive 10 bit ADC analog interface...
