I am working on a lin VCA. Nothing special, straight forward with LM13700. 
But... there is a tradeoff between THD and S/N ratio. For what distortion 
should i go? I can reach 0.1%. with selectd 13700. Or even better with lower 
differntila input.
Should there be different distortin between Log and lin VCA? Because lin are 
mostly used for VC processing and log for audio.
