Ready-to-Use Solutions for Buttons, Sliders, Wheels and Proximity


Whether you are new to developing touch-enabled designs, or just looking for a quick, easy and reliable solution for your design, our turnkey capacitive touch controllers provide a simple and straightforward pathway for implementing touch capabilities in your user interface. These devices communicate with the host via GPIO or the standard I2C, SPI and USB serial interfaces. You don’t need any programming experience to get them working. Simply connect the sensor and apply power. Use the simple Graphical User Interface (GUI)-based configuration tool to tune the controller and monitor the touch signals. These plug-and-play products also enable you to easily replace mechanical buttons in your existing product. We have options that support up to 64 buttons, water-tolerant touch and EN/IEC 60730 requirements for Class B Safety.

Use the links below to find the right solution for your next product:

MTCH10x Family

  • One to eight sensing channels
  • Digital output
  • Water-tolerant touch
  • Simple tuning process
  • Direct replacement of mechanical buttons

CAP1xx Family

  • Three to 14 sensing channels
  • I2C interface
  • Water-tolerant touch
  • LED driver with high-resolution Pulse-Width Modulation (PWM)

AT42QTxxxx Family

  • One to 64 sensing channels
  • UART/SPI/I2C interface
  • EN/IEC 60730 certification on select devices for Class B Safety in white goods

Is a Microcontroller a Better Option for Your Design?


We also offer a wide range of 8-, 16- and 32-bit microcontrollers (MCUs) with dedicated on-chip touch peripherals and easy-to-use code configurators to make it easy to create an integrated touch solution.
