The capacitive touch sensor  has a 2.5 mm thick ABS sheet above the touch sensor.

Could you please suggest any capacitive touch sensor IC's ?

The dimensions of the design are

  1. the diameter of inner circle ( button) is 16mm
  2. The spacing between capacitive pads are 0.9 mm
  3. length of the pads 9.27mm
  4. area of each pad  is 70.84 mm2

Thank-you

Warm Regards

Harini Krishna

Hi

Cypress recommends you to use PSoC 4000S/ PSOC 4100S/ PSoC4100S plus family devices for developing capacitive sensing applications. These suggested families have latest generation of CapSense IP.

Among these families you can choose one based on other requirements of your application.

Please go through following application note for more information.
