EVAL-ADAU1467 - documentation errata
Hi
Customer asked me if there is any more documentation for EVAL-ADAU1467 than on analog.com.
Revision UG-1134 available on a website contains errors
page 33 (switched labels on lines ) - SDATA_IN1 line is crossed with LRCLK_IN1/MP11
no information how AD1937 is connected
D7 is connected to MP14, while on picture (page 27) there is label WRITEBACK – anyhow toggling MP14 doesn’t lit D7 LED
signal MP12 should be on header J3 pin4 – however J3 has only 3 pins (page 26)
Signal MP5 should be on TP56 (page 26) – but there is no TP56 further on schematic
Searched also on analog.wiki – but without success
Any help is appreciated

AD support, this really needs to be answered. The EVAL board has gone to Rev.B with numerous changes which you can find by digging around for posts regarding the ADAU1467, but the User Guide on the website is still referencing Rev.A. This part is way too complex not to have better information available. It has been extremely frustrating just to track down the information to activate ALL of the available inputs and outputs on the board. This information really needs to be clearly laid out in the User Guide, along with a download link for a starter project that has all the functionality working.
My apologies. Below is a link to the schematics for the Rev B evaluation board (EVAL-ADAU1467Z). I will upload an annotated example project shortly,

Thank you Ken!
Attached is an example with all of the audio I/O correctly configured. Please let me know if you have any further questions.
