I got into the Spice modeling business several years ago when I had a need for a model of a chip that a client wanted me to design an interface to. No model existed, so I rolled my own. That turned into a hobby... amusing myself by how compactly I could model the essence of an OpAmp... often as little as one to two lines in a subcircuit.
The hobby has now become a business, nearly 80% of my workload... great, because the chip business has migrated to needing only very low power analog interfaces into digital processing :-( Which interfaces I design for a number of small medically-oriented chip houses.
As for what I announced here... I don't pick part numbers out of the air... how could I know what people need? Like most of the models on my Device Models & Subcircuits Page this was from a post on the LTspice List... nobody could get the Microchip model to run on LTspice... so I took that as a challenge... and succeeded ;-)
Most of what I'm doing now isn't so simple... humongous complicated functions where companies need to present a model that doesn't divulge their IP, yet simulates smoothly on ALL platforms.
Inquiries welcome ;-) ...Jim Thompson
