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.

Mine is a single supply operation and my input is falling in the common mode range.Please correct me if I am wrong.

O/P is also falling in the correct range.

May I know where I went wrong.

Regards

HARI

Hari,

Try ctrl-shift-D and output is as you expect.

Ctrl-shift-T result is zero which is impressive because your current source IPD is a 1 ampere step. An ideal amplifier would output -20kV
