hi c,
I will now ask you a question about your project.

Run this edited version of the LTS and tell me why the current values are the same, when the OPA is deleted.?

E
You asked a very fascinating question sir, but I have never heard before the reason why they remained the same...

Maybe it is because the op-amp is used to amplify weak electric signals. The aim of the op-amp is not to change current or voltage values.

My question is, what does it mean "NI Input" and "NIv" which you used in your .asc design

hi c,
Some bedtime reading about OPA's
Copy and read this PDF, save it in your PC's Technical Data folder.

Hint: an OPA has INV and NI inputs.

E
I'm very happy to see this detailed explanation pdf about it.

This evening I'm gonna start to read to learn more about it.
