I have downloaded the SPICE model file for the OP177 but found that it actually contains the model for the OP1177.
Where can I get the proper SPICE model file for the OP177 ?
Just eyeballing trace2, signal gain is one, but noise gain is 50?
Did you look at AD629 or the newer AD8479??
DIL-8 is a sever restriction. We haven't done any new DIPs in 10 years.
Good luck w/ your design.
That is surely ok for the electronics industry but it's a pity for the (elderly) hobbyist because it excludes him from participation in the latest technical progress in electronic circuitry in his DIY projects.
Thanks a lot for your supportive hints.
PS.: It would still be nice, if AD's SPICE model files would contain the model of the OpAmp that the filename suggests. In the case of the OP177 the model of the OP1177 contained therein is available separately as OP1177.cir anyway.
