[sdiy] TDA7052A as VCA

[anthony]

This thread reminds me of my idea to use uPC1406HA's as a VCA in a 
compressor or just a VCA in general, after I found two of them when I was 
dismantling some old digital cable boxes for parts. They have a log response 
too.

I've collected a number of TDA7052's - all part of developing my technique 
for salvaging surface-mount parts. There are a lot of low-power amp IC's 
that have a voltage-controlled volume control circuit. I think most of them 
have a log response.
