Where is the cathode of EVAL-AD5535BSDZ's output voltage(V0-V31)?
But the cathode is not the output voltage V0-V31's cathode. I need the output voltage V0-V31's cathode.
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
Looks like you are looking for the ground where the outputs are referred to.
you can use any of the encircled pins.
