I am currently evaluating EVAL-AD5660 and i am getting erroneous output in the GUI reading of the voltage. At full scale, I am getting a 2.75V reading but the device should only have a 2.5V full scale reading. (Vref = 1.249V).
I have checked the parameters of the units involved and everything in the hardware part seems to be working out just fine. May i ask for the source code of the evaluation software and the source code of the firmware of the evaluation board? I would like to see if the program/look-up table used in in par with the hardware settings.
