Summary

CL opamps do not model Vout vs. Iout!

Simulate > DC Sweep > Run DC Sweep

shows that Iout can exceed 100mA. A real TL082 does not do this.

Note also that the opamp appears to draw no supply or output load current!


Description

The following links to articles illustrate the complexity that macromodels can reach for accurate modelling:

This is another excellent tutorial:

(BTW, QUCS is a FOSS simulation tool: http:/// )
