The CSD2x User Module (Capacitive Sensing using a Sigma-Delta Modulator) gives capacitance sensing using the switched capacitor technique with a sigma-delta modulator to convert the sensing switched capacitor current to digital code. The CSD2x User Module can support single-channel CapSense scanning and dual-channel CapSense scanning.
