Overview of QT1103-ISG
Capacitive Touch Buttons, Slider 32-QFN (5x5)
Application
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.
