I am simulating an opamp circuit in TINA-TI. I am facing the below issues. Please advise.
1. The simulation(Transient/AC Analysis) takes a long time to run (nearly 45mins to 1Hrs). For this small circuit, will it take such a long time?
2. At the end, I am getting this error (U3.DINN). How to resolve this error?
3. In which scenario this error comes?
