LDC2114 Evaluation Module for Inductive Touch
Inductance to Digital Converter
1 Overview
The LDC2114 EVM demonstrates the use of inductive sensing technology to sense and measure the
presence or position of conductive target objects, and to detect the press of an inductive touch button. The
LDC is controlled by an MSP430, which interfaces to a host computer.
The LDC2112 is the two-channel version of the LDC2114. The LDC2112 does not have a dedicated EVM.
Instead, the four-channel LDC2114 EVM should be used to evaluate the technology and performance.

PCB perforations allow removal of the microcontroller, so that a different microcontroller can be
connected.
This user guide covers the following EVMs:
