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 ?
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.
Thanks for contributing a response to this thread! I noticed that this question was also posted in the Audio community with a response containing more details. Here's the link: ADAU1772 noise cancelling application issue.
