SX8661 - Capacitive Button Touch and Proximity Controller

Description

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

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.

SX8661 Low Power, Capacitive Button Touch and Proximity Controller (8 sensors) with LED Drivers and 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 100pF.
