Capacitive Touch Solutions for Touchpads and Touchscreens

2D Touch Surface Library for Microcontrollers and Turnkey Multi-Touch Touchscreen Controllers

Improve the user experience by creating a smartphone-like user interface for your product. We make it easy to implement finger tracking and surface gesture recognition in a wide array of consumer, medical, industrial, automotive and other applications. Our solutions not only reduce your time to market, but they also offer integrated features, reduce power consumption and are available in small footprints to fit into the most confined spaces.

If you want to add a small touchpad or a touchscreen to an application that uses an 8-bit PIC® or AVR® microcontroller (MCU) or a 32-bit SAM MCU, then our 2D Touch Surface Library is a cost-effective solution that enables you to configure a touch design directly from that MCU. You can provide your customers with the convenience of swipes, taps, and pinch/zoom gestures without adding significant development effort and cost to your product. The 2D Touch Surface Library’s phone-like user interface elements eliminate the need to invest in the infrastructure to run an operating system on your device.

If you are looking for a stand-alone solution to support single-, multi- or gloved-finger operation on touchpads and touchscreens up to 24” in diagonal size, then our portfolio of maXTouch® touchscreen controllers offers high accuracy and report rate, outstanding noise immunity and exceptional touch performance in wet environments, even through gloved fingers and thick cover lens (glass and PMMA), in a variety of automotive and industrial applications.
