Isolated Motor Control Feedback Using the ADSP-CM402F/ADSP-CM403F/ ADSP-CM407F/ADSP-CM408F Sinc Filters and the AD7403 (AN-1265 Application Note)

The sinc filter generates a high-fidelity feedback signal for the motor control algorithm, and it provides rapid detection of overload currents in the case of fault conditions. In this application note, the key capabilities of the sinc filter module and how to set up the software are described. Moreover, the document introduces the main features of the sinc filters of the ADSP-CM402F/ADSP-CM403F/ADSP-CM407F/ ADSP-CM408F microprocessors, with a focus on high-performance motor control applications.
