[biomed12]

Hello,

I need spice models of opamps which are in title for Orcad. I found 2251's from texas's web site but it doesnt work. It gives an error like "Model U_X1 used by .... is undefined"

Thanks

Try these, not tested by me.

These are generic spice models.

The 2277 is just the dual of the 277
