Overview
lQ QT1103 QTOUCH™ 10-KEY SENSOR IC This datasheet is applicable to all revision 3 chips DETECT SYNC/LP VSS SNS7K SNS7 SNS6K SNS6 SNS5K The QT1103 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 on plastic film.
