Re: icl8038 , 8038



see that pot at the top of the demo circuit? By deliberately
unbalencing it, things shift in symmetry from reverse ramp to
triangle to ramp.

on 2206 they call it distortion correction, on 8038 its symmetry, my
bad!

I wish I knew as much about analog as I used to, too many years
setting on my posterior supporting the grad students, I've forgotten
too much basic EE. Too much time teaching chemists and chemical
engineers to measure currents and use a scope, and not enough time
with the old pencil and paper. WAY too much time in teh machine shop,
and wayyyyyy too much time adapting off the shelf stuff to do the
research. I need to get back to the basics and the soldering iron.

I still like the challenge in the idea of designing the drop in
replacement in smd, although matching the transistors might be a
little hard with just a heathkit curve tracer.

Now to find a chip designer to tell me if all the betas are similar
ie standard cells, from transistor to transistor on that design, or if
they did a lot of altering things.
