Where is the cathode of EVAL-AD5535BSDZ's output voltage?

Hi,

Please refer to this figure below.

And I chose your identified cathode as the cathode of output voltage V0-V31's cathode, the  measured value of output voltage V0-V31 is not the calculated value based formula of datasheet of AD5535B.  The formula is
