This reference design uses our inductance-to-digital converter technology to provide a high-precision method to sense button presses on a metal surface and our haptic drivers provide high-quality haptics feedback to the user. TIDA-00314 demonstrates techniques for system design, environmental compensation and electromagnetic interference protection.
Watch the TIDA-00314 overview video on the touch-on-metal buttons with integrated haptic feedback.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
