8-KEY QTOUCH SENSOR IC

lQ This datasheet is applicable to all revision 1 chips SYNC/LP VSS DETECT SNS7K SNS7 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.
