Re: Wanted: LM-709 (Spice model) National Op-Amp

Well, according to you, I'm not a expert on SPICE, never said I was,
but I think your missing the point of my POST Kev!! I'm not really
interested in Spice Programs per say, only the search for the model of
the 709 OP-Amp

cut and dry and that is it..............:)

How do you propose to design a 1000 transistor circuit?

Geez...... where did this come from? I'm only agreeing with bob's
quotes from his book. I'm a spice user myself. I wouldn't want to wager
on spice either, I'm almost confident that something will go wrong, if
I rely on it too much. Circuit temperature is one reason to use another
more practical approach, and this is not unrealistic, you can
understand what my reasons are for doing this. Even though this can be
done in spice, and It's a nice contribution and a big help, this where
I draw the line!! I have seen particular circuit behaviors, in which
spice is unable to predict very well. just my opinion.

A 10,000 transistor circuit?

Must be one hell of an OP-Amp!! huh? :)
