Hello. We have evaluation board ADAU1966Z.
It marked on top ADAU196xZ , revision : B , Revision date :150317.
Seems that documentation UG-416 and board ADAU196xZ have differences, see attached pictures.
Components installed in different places. For example in documentation UG-416 component U9 must be LM317, but it is not LM317, see pic 2.jpg
Can you provide relevant documentation on existing board ? thank you.
I apologize for the confusion. We updated the PCBs to improve the functionality but the user guide has not been updated. I am still in the process of updating the 196xA user guides and will do the 196x user guides soon. Meanwhile, the 196xA user guide will be very useful for you. The only differences in these eval boards is that the ADAU1966 runs on 5V AVDD instead of 3.3V. So the power supply section of the eval board is slightly different. I will look for those details and post them. But meanwhile I will attach the preliminary user guide for the 196xA parts so you will know how to use your board. The first half of this user guide is for the RevA boards so you will need to go about halfway into the document to get to the RevB (called Rev C for the 196xA).
Is there any other update to this? The 150317 board that I have has at least two additional switches, S11 and S12 that are not shown in the schematic. The Silk is labeled HPINR DAC2 OPUT2 for S12 and HPINL DAC1 OUT1 for S11
Can you take a picture of the board? Take a decent resolution picture or two so I can read the silk screen and see the entire board as well. Then zip up the file and attach the zipped folder. If you just attach the picture the resolution is changed by the forum software and is not very useful for zooming in.
I have the old and new revision boards at my desk and this does not sound like either of them.
Thanks Dave. The switches in question are right above the S10 Addr[1:0] switchadau169xz.zip
