Because the data sheet explain the ADAU1772 can use noise cancelling application

and 15mw power consumption for typical noise cancelling solution.

Could you tell me that the ADAU1772 have built in noise cancelling algorithm or not ?

Thank you.

From my understanding the ADAU1772 uses low-pass\high-pass\band-pass filters to create the cancellation signal. I can't see any mention of any adaptive filtering techniques in the documentation.
