SPICE Model for STM32L4 OpAmp ?

[ValereAq]

We need to perform some SPICE (LTSpice most likely) simulation of analog circuitry using the STM32L4 OpAmp (TQFP package not BGA).

I can only find this IBIS model, which will not help me much for this analog case, and not the SPICE model, which would help a lot.

Where could I find the Spise Model of the STM32L4 OpAmp when used as "standalone" will all the IO pins output on MCU external pins (both in "normal mode" and "low power mode") ? Would it be possible to get it or to get support to create it ?

Thanks.

Bonjour @ValereAq et Bienvenue :smiling_face_with_smiling_eyes:

In fact, the Spice Model of the STM32L4 OPAMP is not available. But you could use standard OPAMP model just setting its parameters as given in datasheet of your MCU (for example the table 82 of the DS12469). The parameters depend on the settings you choose for the OPAMP. Then you can use it for simulation.

Best Regards.

Thanks,

I will test like this creating a model with the datasheet specifications.

I was interested to perform phase stability simulation also trying to introduce  temperature shift, this is why I was searching if a more advance model were available.

Best regards.
