Overview

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. The device can also be configured at different duty cycles to reduce power consumption.

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

  • USB A - micro USB cable
  • Sensor interconnect cable WM11299-ND
Inductive sensor AFEs
LDC2112 — 2-Ch inductance to digital converter with baseline tracking for low power touch buttons LDC2114 — 4-Ch inductance to digital converter with baseline tracking for low power touch buttons
