Customer want to know the reason why in his simulation, they cannot get the correct output when using OPA191 as inverting. Below is the details.
I am using an OPA191 IN my design and trying to connect a voltage divider bias output to inverting input of the op-amp. I am not getting proper output.
If I put a buffer in-between I could get the output as expected or If I go for a non inverting configuration also the output will be as per my expectation.
I know it could be a a design mistake however if you help me to understand what is the cause behind that
Kindly refer to attached TINA: trial (1).TSC
Thank you in advance.
