Dear all,
I have a little problem during testing the Ramp example. I used ad5940,adicup3029 (Evaluation board) and crocodile clip cable.
I configured hardware by referring to this site(AN-1563 (Rev. 0) (analog.com))
I constructed the circuit & coding like a picture
and the result is the following picture.
This is the same result as connecting resistance only.
I think this is a problem caused by cap and diode or ad5940's hardware configuration.
How this could be fixed?
+ The link mentioned earlier contains the Rtia formula for all examples except amperometry. What should I refer to?
