QT1081

8-KEY QTOUCH™ SENSOR IC

The QT1081 is an improved, lower cost, simplified circuit version of the

popular QT1080 sensor IC. The QT1081 is designed for low cost

appliance, mobile, and consumer electronics applications.

QTouch™ technology is a type of patented charge-transfer sensing

method well known for its robust, stable, EMC-resistant characteristics.

It is the only all-digital capacitive sensing technology in the market

today. This technology has over a decade of applications experience

spanning thousands of designs.

QTouch™ sensors employ a single reference capacitor tied to two pins

of the chip for each sensing key; a signal trace leads from one of the

pins to the sensing electrode which forms the key. The sensing

electrode can be a simple solid shape such as a rectangle or circle. An

LED can be placed near or inside the solid circle for illumination.

OUT_7 32

The key electrodes can be designed into a conventional printed circuit

board (PCB) or flexible printed circuit board (FPCB) as a copper

pattern, or as printed conductive ink.

The QT1081 is also compatible with clear films to make simple

button-style touch screens over LCD displays.
