TINA/Spice/OPA2333p: AC specification measurement

Part Number: OPA2333P
Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models

Hi,
I confirmed AC specification by using following simple circuit.
However, I observed strange behavior over Cload = 440pF

Could you please confirm why we observed such strange behavior ?

I think what you're seeing there it's not a problem. I have found in the past with any simulators (nothing to do with model specific) that is when I simulated high-Q system, sometimes the phase were being "folded" by 360 degree depending on the simulators. I think what's happening there is that since it is folded by 360 degree.. from the mathematical view point either solution is valid or it satisfies the mathematical equations.
