ADA4700 Spice Model do not work "Missing node(s)"

The Spice Model do not work

The error is missing node(s)

  • Hi,

    What simulation platform are you using? Can you share your schematic.

    Thanks,

  • Hello Volker,

    Did you directly downloaded the spice model from the product webpage?

    I believe you may have accidentally modify the spice model while you are exporting it. I ran a quick test of the model in a buffer configuration and it works fine. If you are certain that the ADA4700 model is the problem in your circuit, you can try to download a new model from our website and export it carefully with your prefered simulator.

    I also check the model in our own simulator and it run smoothly in simple buffer configuration. You can try our ADIsimPE for your simulation needs if you like.

    Regards,

    Phil

  • Hallo

    I use EAGLE to draw
    and export a Spice Netlist

    Than I import the netlist in LTSpice

    The netlist

    .op

    .tran 0 100m

    .include C:/EAGLE/cir/ADA4700.cir

    * Pinorder: A K

    XD1  N9 OUT 1N4148

    .INCLUDE C:/EAGLE/cir/1N4148.mod

    * Pinorder: I+ I- V+ V- O
