Hi,

Is there a way to get the OPA320S spice model into the pSpice-for-TI library? I cannot find it.

thanks and best regards

Hi Tiemo,

Please check the link below. PSpice model should be compatible with Cadence model, which is pSpice-for-TI.

Below is the Tina model.

Yes, but like a lot of the models it does not support the shutdown feature. There are many more models that do not, than do. The feature is very problematic in the macro models.

Hi Tiemo,

Michael is correct. The PSpice, which is a behavior Macro-model (Green-Williams-Lis), does not support shutdown pin simulation, which is considered as logic model.

Thank you for your comments.
So this means that der is no OPA320S model for "TI pSpice". Only the OPA320 does exist.

Hi Tiemo,

Yes, there is only one PSpice model. So there is no model for OPA320S (same die), which it has an extra shutdown pin.

If you have additional questions, please let us know.

Best,

Raymond
