SX8661 - Capacitive Button Touch and Proximity Controller

General Description

The SX8661 is an ultra low power, fully integrated 8channel solution for capacitive touch-button and proximity detection applications.

Key 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 SX8661 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.

Analog Output ADVANCED COMMUNICATIONS & SENSING DATASHEET 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 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 SX8661 includes a capacitive 10 bit ADC analog interface with automatic compensation up to 1
