[sdiy] high quality expo VCA

[Fernando de Izuzquiza]

Hola list.
I've found a complete high quality expo VCA.
Schematics: http://www.radio-flier.com/PDF%20Files/RFE117Sch.pdf
Manual: http://www.radio-flier.com/PDF%20Files/RFE117Man.pdf
It looks great. (BurrBrown for the control path, that's luxe!) No PCB?

But still looking for a good VCA with expo/lin switchable response...

Has anyone designed an expo circuit with the SSM2164? We have Mike Irwin LIN design, and the chip is
originally expo so... it would be nice to switch between the two responses.


Fernando
