Currently, I am trying to evaluate EVAL-ADAU1977.
I downloaded the following evaluation software, but it does not work on my PC.

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.

How can I still use standard microphoens with the ADAU1979?
Hello Dave T,
Thanks for your info! I try out the ADAU1977 first!
