    Hi User,

    I have no issues with the spice model. Do you have a schematic to share?

    What is the simulator you are using?

    I use this spice model which down from TI, to creat a component in Multisim 14.0。Error occurs with the Red description。

    Hi,

    This model was created to work with pspice, tina-ti and, pspice for TI. There is no error with that line in pspice because it is an ideal op amp.

    I do not think this way of modeling is friendly to modelsim. I would recommend to use the model with pspice for TI available for free.
