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 circuits are renowned for simplicity, reliability, ease of design,
and cost effectiveness.
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.
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.
