  • Hi, Venkat,

    There are several ways to remove noise due to the MIC data.

    1. Make sure that the input MIC data is well regulated. A differential microphone ensures that the noise level will be minimal.
    2. The internal processing blocks can be used to improve the signal quality. You may change the processing block in order to determine what block can be used for the best performance.
    3. You may add an external low-pass filter in order to eliminate the out-of-band noise. Please take a look of the following document: http://www.ti.com/lit/an/slaa313/slaa313.pdf. An RC low pass filter (R=1k, C=4.7nF) is often suggested.

    Please let me know if the problem persists.

    Best regards,
