into my system to two ADAU1977s.  I have a single microphone that needs to
connect to one input on each ADAU1977.  How can I connect the single
microphone to the two…

Hello,

Currently, I am trying to evaluate EVAL-ADAU1977.

Hi all.

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?

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?
