[sdiy] Linearising VCAs - Mike Sims' EDN article

[Robin Whittle]

I have not read the extensive discussion in recent months about
VCAs, so perhaps some of this has already been mentioned.

I read in Tony Allgood's doco:

  http://www.oakleysound.com/vca2-doc.pdf

of a linearisation technique for an LM13600 dual VCA.  This lead me
to the article by Mike Sims, of Lectrosonics, in EDN 19 January 1995:

Also of potential interest:

  The BA6110 datasheet.  I couldn't find a BA662 datasheet.

  Using a BA6110 in place of a BA662.
