Dear Team,

Below is a TIA using OPA320.


I am expecting an output voltage of 3-(4u*20K) = 2.9V ,but obtained a value of Zero.

The current source value is 4uA but it is measured as 1A.

May I know what is the issue.

I get the following with a lower bias than you had :



Seems like this part claim RRIO does not want input Vref close to its + rail, if one plays around
with diode Voffset and the +Vref....but then I would do the DC analysis by hand to get what
T(DC) should be..
