Hello,
I need to use a uA741 op amp for my simulation but i cannot find it anywhere. I saw that many people use instead the LM741. Are they the same? What are the main differences? Anyway, I saw that a model for the uA741 was available in the TI site ( https://www.ti.com/product/UA741 ) but that model made the simulation impossible (i needed to simulate 5 seconds and it was capable to simulate just few micro second at a time, so it took an eternity to simulate...). In the same site i also found the model for the LM741 but it was in a completely different format and i was not able to actually use it. And finally, in a thread in this site ( https://forum.allaboutcircuits.com/threads/how-to-add-op-amp-741-to-lt-spice.139069/ ) I found tha another model for the LT741: the simulation time was ok but in a buffer configuration (output shortcircuited to the inverting input) it was not able to actually follow the voltage in the non inverting input correctly (maybe the op amp is just not suitable for this configuration?).
What should I do?
Thank you in advance!
