ahdlLib opamp model vref pin

olalivier
Hi there, I try to use the opamp model from ahdlLib but there's a few point about the model I don't understand... 1. what are ibias and iin_max parameters ? 2. Is vsoft used for output clipping ? Concerning the pins, I really don't understand the point of vref...? I can't find a decent doc about the model and the code does not provide explanations... Can you please help me on this one and if needed tell me which other opamp with a slew rate limited output i can use. Thnak you very much. Olivier

  • Hi Andrew and thank you very much for your answer. I do understand what you say about "pretty old" models but this brings a question, if I may. Is there a recent version of these libs or a modern approach to model this kind of devices without doing it myself. I know VHDL-AMS and I'm pretty sure I can do the same and tailor a device that does what I need but wouldn't it be more efficient to have something from lib ??
