The FDC1004QEVM is a development tool used to measure capacitive touch sensors. It offers a precision capacitance-to-digital conversion solution that makes use of the Sensor- ISFDC1004Q capacitive sensing integrated circuit (IC) featuring high accuracy, low power operation, and small packaging size. The evaluation board offers four signal input channels, two calibration capacitors, as well as a timer/counter to read the leakage currents of the capacitive touch samples. It can accurately measure capacitive touch sensors over the wide range of capacitance values from picoFarads to microFarads. Additionally, the FDC1004QEVM offers a fast response time of less than 1 millisecond.

The application field of the FDC1004QEVM evaluation board includes capacitive touch solutions such as proximity sensing, touch sensing as well as slide and wheel sensing. It is thus a valuable evaluation tool for developers, aiding in the development and characterization of capacitive sensing solutions. The FDC1004QEVM can be used to measure different parameters of a capacitive sensor, including capacitance, current leakage, and response time.

The FDC1004QEVM evaluation board works by converting capacitance values into a digital output code. This is achieved through a charge transfer process, wherein the charge is transferred from the input electrodes or capacitors to the reference capacitor. These charges are then measured and converted into a digital value representing the capacitance. The charge transfer process requires regular calibration for accuracy. This is done by the reference capacitor mounted on the board, which acts as a reference of the capacitance value.

The FDC1004QEVM evaluation board also includes a timer/counter that can be used to measure leakage currents or transient signals from a capacitive sensor. The timer/counter can measure both short and long duration signals with a high degree of accuracy. This helps in better characterization and tuning of the capacitive sensors.

In conclusion, the FDC1004QEVM evaluation board is a great tool for characterizing capacitive touch sensing solutions. It offers a precision capacitance-to-digital conversion solution, four signal input channels, two calibration capacitors, and a timer/counter to read leakage currents. The application field for this evaluation board includes proximity sensing, touch sensing and slide and wheel sensing. It is thus an important and useful tool for developers as it helps them to develop and characterize capacitive sensing solutions.
