Key Document


The LDC2114EVM (Evaluation Module) demonstrates the use of inductive sensing to detect a button press on a monolithic piece of metal.  The EVM can connect up to 4 buttons using the LDCTOUCHCOMCOILEVM or customized coils designed through Webench.  Button presses & levels of pressure are indicated by onboard LEDs to indicated through onboard LEDs.  The device can also be configured at different duty cycles to reduce power consumption.

  • <7µA at 0.625 samples per second
  • Up to 4 buttons supported
  • Dedicated button logic outputs
  • Integrated and configurable algorithms for button press detection

What's Included

  • USB A - micro USB cable
  • Sensor interconnect cable WM11299-ND
