Hi all,
Can someone explain to me what's wrong here? Or let me know what other information you need to help me figure out what going on? I used the LME49710 model in pSPICE, but it gives me these errors:
WARNING(ORPSIM-15256): <X_U1.XRgn2.ROHMS> not a subcircuit param
WARNING(ORPSIM-15256): <X_U1.XRgnd3.ROHMS> not a subcircuit param
ERROR -- EVALUATION VERSION analog Node Limit (75 Nodes) Exceeded!
I'm using the Lite version of Orcad Capture but I've only placed 5 elements in the circuit I'm trying to simulate. So I'm confused why it's saying the Node limit is exceeded. Maybe it has something to do with the model for the LME49710 audio amp? I've uploaded my .out file as well as a screenshot of the circuit I'm trying to simulate.
