I want to simulate the AD797 component on LTSpice.
I have download the Spice model on Analog Device website, but it's a LTspice Netlist file (ad797.cir). How can I import it under LTspice? When I open it with LTspice, it's a text document.
Thanks for your feedback.
This model has an extra pin for compensation compared to many other opamps. I have simply added one pin to the symbol "opamp2.asy" and saved it with a different name. There are 4 different…
This model has an extra pin for compensation compared to many other opamps. I have simply added one pin to the symbol "opamp2.asy" and saved it with a different name. There are 4 different model files. The difference is mostly regarding (offset) bias current and offset voltage.
Just unzip my file in any directory to run the simulation.
I recommend to copy the symbol(.asy) file and the model(.cir) file to the folder of your schematic.
I had a problem with your file, but doesn't matter, I've used a AD795 for the simulation and it was worked.
Just a quick question to finish, do you know if there is an equivalent component from Analog Device for the amplifier INA111 please? It's not very important if it doesn't have exactly the same characteristics.
Thank you in advance,
My previously attached example from "AD797_test.zip" will work with LTspiceXVII on every PC without any modification. Just unzip and RUN the simulation. I can't believe that it will not work on your PC.
Ok, I will try again this afternoon. Can you just answer my last question please?
Have a good day.
The AD8220 looks very similar. It also has a JFET input stage. It's directly available in LTspiceXVII.
Thank you helmuts
