OneTouch

Human interfaces are sophisticated. But not every application requires a customized solution. That’s why we’ve created our OneTouch solution. It gives OEMs and OEDs a cost-effective, simple and flexible option for human interfaces. Our OneTouch solution consists of a family of capacitive sensing chips, easy to use GUI-based design and development tools, and documentation that guides you through the entire process from concept to mass production.

The configurable, turnkey OneTouch solution leverages Synaptics' capacitive interface expertise with a focus on design integration and usability considerations, sensitivity tuning, and board testing. Our goal is to ensure manufacturability with high yield. Expert local and factory technical support is available to you throughout the entire process.

Synaptics OneTouch chips use a proprietary mixed-signal technology to sense capacitance on sensor electrodes with high accuracy.

  • Capacitive buttons are created with single or multiple electrode sensors.
  • Scroll strips are recognized using multiple sensor electrode/sensor pin combinations.
  • GPIOs can be used to drive LEDs, to monitor mechanical input switches and dome switches, or as general purpose I/Os.
  • Synaptics OneTouch chips support industry-standard interfaces to communicate with host processors for optimal interoperability.
