Simulation Issue

Silverwolfman
Silverwolfman over 6 years ago

Hi It is my first time using Pspice simulation and I encountered some issues. 

Could anyone help me to take a look if there is anything I didn't config correctly in the spice model?

Thx.

    LMH6553 model is not compatible for PSpice. I assume you are using model downloaded from TI.com.  Following line in model 

    rtc a108 vee 14.3 tc1=400e-6 tc2=-5e-6

    is troubling PSpice. 

    This syntax is not supported by PSpice. simplest fix would be modify this line model as following

    rtc a108 vee 14.3 ;tc1=400e-6 tc2=-5e-6

    this will exclude two temperature coefficient from model. 

    If you wish to include these modify the above line as following 

    rtc a108 vee 14.3 tc=400e-6, -5e-6
