OPA2197: About OPAx197 Pspice model(Rev.D)

Part Number: OPA2197

Hi Team,

 

Our customer would like to simulate phase margin by LT Spice.

Currently, they use “OPAx197 Pspice model(Rev.D)”.

 

However, they can’t simulate phase margin.

Is it possible to check the phase margin with " OPAx197 Pspice model(Rev.D "?

And, could you please let us know workaround if you have any idea?

 

[Supplementary information]

-The actual file is "OPA2197_diffamp_phase_margin.asc”

-Other companies' models can check the phase margin with the same simulation circuit.
