Spice Model for OPA564

Other Parts Discussed in Thread: OPA564

Hi Thomas, Hi list,

My customer is looking for a spice model of the OPA564.

They plan to use the part in a Power Line Communication Applikation (as recommended for the part)

Do you have something available? -> Preliminary model or a model from a OPA with similar behaviour would be fine (intention is a frist evaluation in simulation)

Thanks for your help

    Hi Uli,

    I just received the new OPA564 simulation model from the model builder today. Since I just received it I haven't had an opportunity to test it yet. If your customer's need is immediate I can send you this model with the understanding that it is "preliminary" at this point. That said, they are usually good to go right from the start.

    Regards, Thomas

    Hi Thomas,

    thanks for the quick answer. I talked to the customer and it is understood and OK for him.

    This would be a normal Spice model (Test file / net list), right?. -> He is using a commercial Spice Simulator and not Tina for his Simulations.

    Therefore can you send me the model please?

    Regards, Uli

    Hi Uli,

    Indeed the file contains a PSpice syntax listing. The customer should be able to import it into their particular simulator's macro builder or wizard.

    Since this is a preliminary model at this point, I will send it to you directly. It will not be provided for general use until we have had a chance to thoroughly test the model. I would be interested in hearing about the customer's experience with the new OPA564 model once they have performed some simulations.

    Regards, Thomas

    Hi Thomas,

    thanks for the quick answers.

    The customer integrated the model already successful in their simulaton.

    One question now just came up:

    Is it possible to use the model with reliable results using a unipolar VCC?

    Thanks for your help

    Hello Uli,

    Yes, the OPA564 Spice model is useable in unipolar, single-supply configurations. Just make sure that all of the pin functions are properly biased for such operation.

    I just ran some simpleTINA Spice simulations with the OPA564 model connected in a single-supply configuration and didn't have any problems.

    Regards, Thomas
