[sdiy] Quad VCA design

[David G Dixon]

I have used V2164 in virtually every module I've designed in the last three
years, and it's brilliant.  It has its quirks (you will get very familiar
with the fine print of the datasheet, especially if you try to do
unconventional stuff with it), but it is a solid performer.  Just don't try
to power it up backwards.  Unlike most opamps, it will self-destruct
instantly (as would the SSM2164).
