QST608
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
Applications
This device specifically targets human interfaces
and front panels for a wide range of applications
such as PC peripherals, home entertainment
systems, gaming devices, lighting and appliance
controls, remote controls, etc.
QST devices are designed to replace mechanical
switching/control devices and the reduced
number of moving parts in the end product
provides the following advantages:
Lower customer service costs
Reduced manufacturing costs
Increased product lifetime
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 charge-
transfer (QProx™) capacitive technology.
QTouch™ and QProx™ are trademarks of the
Quantum Research Group.
