Danf,
Thank you for the help. I have been looking at the AD9748, for which there is an evaluation board (EVB) available described in the datasheet. However, there is not enough information about the EVB in the datasheet describing how to change among different possible output configurations described in the AD9748 datasheet. I wonder if you can point me to the manual or a guide for this evaluation board.
Specifically, I would like to use a configuration described as "differential coupling using an opamp", but by looking at the datasheet it seems that the EVB may not support this configuration which requires an OpAmp.
Thank you
