  • RE: TINA/Spice/OPA445: opa445

    Resolved
    Hi Jeff, The OPA445 uses an older macromodel architecture which may not model voltage or current noise as accurately as the architecture used in newer macromodels. Since it seems that the OPA445 macromodel does model the broadband noise correctly…
