Abstract
The present disclosure relates to an integrated circuit connectable to a microelectromechanical system (MEMS) transducer. The MEMS transducer is configured to generate a transducer audio signal in response to sound. The integrated circuit comprises a digital scrambling circuit coupled to a data communication interface. The digital scrambling circuit is configured to convert a digital audio stream, representative of the transducer audio signal, into a corresponding scrambled data stream. The integrated circuit additionally comprises a data bus interface coupled to the digital scrambling circuit and configured to output the scrambled data stream.
