The ADAU1977 has a built-in Microphone input and Mic Bias circuit. I have a redundant inputinto my system to two ADAU1977s. I have a single microphone that needs toconnect to one input on each ADAU1977. How can I connect the singlemicrophone to the two…
I look for ADAU1977 Digital volume control
information at D.S but not found
Thank you in advance
Currently, I am trying to evaluate EVAL-ADAU1977.
I downloaded the following evaluation software, but it does not work on my PC.
In the codec driver for adau1977, the value for micbias is retrieved from dev->platform data. However, as this article states, if the driver has been instantiated from the device tree code, the platform_data pointer will be null, indicating that the…

Happy Christmas eve Dave,
Thank you for your answer.
I understand that the tABDD on Figure2 in the ADAU1977 data sheet should have been drawn tABDD+1BCLK cycle.
Also, Thank you so much for giving me the very useful formula for my future design…
Comments from the customer:
Reply to post above: I was already aware of what was mentioned in the reply and I really thought that it should have been straight forward to get the device tree working without changing anything in the simple_card driver but…
I have got this info:
HBM: 4kV, CDM:1.25kV
In the SC584-EZLite there are ADAU1977 & ADAU1979.
I would like to connect 8 microphones to the EZLite, 4 to each codec.
However, the ADAU1979 doesn'y have mic bias as ADAU1977.
How can I still use standard microphoens with the ADAU1979?
We are considering the adoption of ADAU1977.
The data sheet of the ADAU1977 does not have a description of the maximum current consumption for each power pin.
Could you tell me the maximum consumption current of each power supply pin?
