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