Hello,

I'm exploring inverting and non inverting op amp circuits

Following a book of mine, I had success with the following circuit using an lmc6001.
However, using an opa320 for example, I can't get any amplified signal out of it

As a function generator I'm using 1Khz with 100mVp

Can someone explain what's going wrong ? How to obtain 10 times the voltage of the input ?

I can't even get it working without capacitors, and setting them to initial 2.5v didn't change anything.
In this example, function generator is set at 10kHz 100mVp amplitude 0 offset.
Here is what I get on the oscilloscope. Channel A is input RED, Channel B is output GREEN

Don't offhand see any reason for it not to work.
What is the polarity of those .ic commands?
Try simulating for at least 500ms to see if anything changes.
 

I ended up with the conclusion that the opa320 spice model is wrong.

In the latest release I see "* Version 3.0 : Correct for single-supply operation", but it doesn't work anyway
