Turnkey Capacitive Touch Controllers

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.
