RETRIEVING DATA FROM THE DDC112.

Other Parts Discussed in Thread: DDC112, DDC11XEVM-PDK

Hi,

I retrieve data from the DDC112 and get 40bit.

The first 20 bits from IN1 and the last 20 bits from IN2.

My question ist:

Where is the difference between "side A" and "side B", of each channel, or is in this case no difference?

Best regards,

Jan Philip

    Hi Jan,

    The DDC112 actually belongs in a different forum - the Medical HiRel forum to be specific.  I'll move it for you but I am wondering what mode you are operating the DDC112 in?  Side A vs side B depends on the state of CONV - take a look at Figures 14 and 15 of the data sheet, that might help to clarify things a little for you.

    Hi Tom,

     

    I knew the conversion details for the Internal Operation of the continuous and the non-continuous mode. I tested the DDC112 with the DDC11xEVM-PDK Performance Demonstration Kit before.

    I use the mode which is described in the Application Bulletin "Retrieving Data From The DDC112" (AB-136) and in this paper is nothing written about side A vs. side B.

     

    Best regards,
