Here is a model from TI. They have a DOS disk full of them, along with a
data book. Get in touch with them at:

Texas Instruments Inc.
Literature Response Center
P.O. Box 809066
Dallas 75380-9066

The name of the box and disk is "Linear Circuits - Operational Amplifier
Macromodels"

* TL072 operational amplifier "macromodel" subcircuit
