FDC2114 and FDC2214 EVM User’s Guide

Overview

The FDC2114/2214 EVM demonstrates the use of capacitive sensing technology to sense and measure

the presence or position of target objects. The EVM contains two example LC tank sensors that are

connected to the FDC2114/2214 input channels. The latter is controlled by an MSP430, which interfaces

to a host computer.

Figure 1. FDC2114/2214 Evaluation Module

The FDC2114/2214EVM includes two example PCB sensors. Each sensor consists of a single-layer

capacitor plate, a 33pF 1% COG/NP0 capacitor, and a 18

μH connected in parallel to form an LC tank.

PCB perforations allow separation of the sensor coils or the microcontroller, so that custom sensors or a

different microcontroller can be connected.
