Hello Holger,

thank you very much for your guidance on how to adapt manufacturer PSPICE models for dual opamp use in the tutorial.

Is there a “generic way” to get dual spice models for eg OPA 1612, 1656 or 1641?

I could make it work with the TL072 , following your description.

I could make it work as well with OPA1656 and TL072 as Spice Model.

But so far , I could not make the OPA1656 Spice Model work with OPA1656

I tried to adapt your TL072-dual.lib for eg OPA1656 (see attachment),

but was not successful. Maybe a syntax error in the dual.lib script or an incompatibility in the manufacturers .lib file?

OPA1656-dual.lib was selected as Spice Model for all three components A,B,C.

Netlist below.

Your advice is much appreciated.

Best Regards;

Frank
