Patented charge-transfer design Up to 8 independent QTouch keys supported Individual key state outputs or I2C interface Fully “debounced” results Patented AKS Adjacent Key Suppression Self-calibration and auto drift compensation Spread-spectrum bursts to reduce EMI Up to 5 general-purpose outputs LQFP32 (7 x 7 mm)
Description
The QST108 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 QST108 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.
