QST104 - Capacitive touch sensor device 4 keys

General Description

The QST104 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.

Key Features

  • Patented charge-transfer design Up to 4 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 13 general-purpose outputs.
