Texas Instruments LP5907 | Demoboard TIDA-00314

Description

This TI Design uses Texas Instruments' inductance-to-digital converter technology to provide a high-precision method to sense button presses on a metal surface and TI's Haptic Drivers provide high quality haptics feedback to the user. TIDA-00314 demonstrates techniques for system design, environmental compensation, and electromagnetic interference protection.
