QST108

Capacitive touch sensor device

8 keys with individual key state outputs or I2C interface

Not For New Design

Features

■ Patented charge-transfer design

■ Up to 8 independent QTouch™ keys supported

■ Individual key state outputs or I C interface

LQFP32 (7x7 mm)

■ 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

Description

The QST108 is the ideal solution for the design of

capacitive touch sensing user interfaces.

■ ECOPACK® (RoHS compliant) package

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.

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:

The QST108 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.

■ Lower customer service costs

■ Reduced manufacturing costs

■ Increased product lifetime
