I downloaded AD8021 Spice model from Analog website and simulated the OpAmp alone and it worked fine. When I put AD8021 model on my Power Amplifier circuit , it crashes and I am not able to see the simulation. I have changed different parameters in LTSpice and I have not being able to get the AD8021 working, however I used to have AD8033 instead and my Power Amplifier circuit was working fine. Do you know why this is happening? Could it be an issue with the AD8021 model?
Thank you for your help,
