Hello,
Like the title said, how can you tell if it's an inverting or non-inverting op amp just by looking the the schematic like this one.
textbook said this is an inverting op amp. I thought whichever input node (+/-) the signal go through dictate the classification of an op amp if it's inverting or non-inverting.
Questions I still have regarding op amp:
Thanks ahead.

Questions I still have regarding op amp:
- Op amp needed feedback (through '-' non-inverting input) to "stabilize" it. What does it means? I'm thinking that since the gains is most often in the magnitude of >100k, the feedback is there to take away some of the amplification so that the amplified voltage could be in the range of the supplied voltage of the op amp.
- what is it mean when the op amp is "saturated"?
Thanks ahead.
