QST608 www.datasheet4u.com Capacitive touch sensor device with rotor or slider plus five extra keys and I2C interface Preliminary Data Features ■ ■ ■ ■ ■ ■ ■ ■ ■ Patented charge-transfer design Rotor (or slider) plus five extra keys Up to five general-purpose outputs I2C interface Fully “debounced” results Patented AKS™ Adjacent Key Suppression Self-calibration and auto drift compensation Spread-spectrum bursts to reduce EMI ECOPACK® (RoHS compliant) packages LQFP32 (7x7 mm) Description The QST608 is the ideal solution for the design of capacitive touch sensing user interfaces. Touch-sensitive controls are increasingly replacing electromechanical switches in home appliances, consumer and mobile electronics, and in computers and peripherals. Capacitive touch controls allow designers to create stylish, functional, and economical designs which are highly valued by consumers, often at lower cost than the electromechanical solutions they replace. The QST608 QTouch™ sensor IC is a pure digital solution based on Quantum's patented chargetransfer (QProx™) capacitive technology. QTouch™ and QProx™ are trademarks of the Quantum Research Group.
