DIGITAL POTENTIOMETERS
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.
