DCPs ENAbLE DIGITALLy CONTROLLED ANALOG SIGNAL PROCESSING

DCPs allow for digital flexibility in an analog circuit. DCPs provide a link between the digital and analog domains in the

system, allowing repeatable control and configuration of analog circuitry. This approach is typically more power-efficient than

computationally intensive digital signal processing. For more information, please see AN133.
