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?
In other words, how do I bias micro[phones with the ADAU1979?
The ADAU1979 does not have any PGA to amplify microphone level signals. That is why it does not have a MicBias output. So you will need to use an external pre-amp or a different ADC/Codec and bring in those signals onto the board.
