    Hi Alix:
    The product of customer needs to be able to support full duplex audio play and sound recording pickup. When the audio is being played, the audio content picked up by the recording is the target audio source and the mix of the audio and ambient background noise.In order to obtain the target audio source clearly, it is necessary to provide the self-playing audio to the audio processing module as the signal reference, so as to filter the known noise (self-playing audio) in the mixed audio picked up by recording. The basic principle is similar to the noise reduction of the mobile phone dual microphone.
    In view of the inevitable phase shift and distortion at the front end and rear ends of the power amplifier IC, the signal reference provided shall be collected from the end of the final acoustic device, so the signal collected from TPA3113D2, than connected to a AD chip: CX20810(microphone array IC).
    TPA3113D2 output power is 2*5W.
    Thanks!

    Regards!

    Hi Eric,

    For this issue, I am thinking that we can talk offline for more details as some experiments may need to be confirm whether added circuits are ok for customer's expectation.

    Can you contact me through email?

    Regards,
    Alix Wan.
