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.

/CHANGE

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.

SNS1K

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.
