Oops, nevermind! I didn't see the crummy distortion specs before sending my<br />

there’s hope that actual figures might be better and this numbers are honest conservative specs.<br />
not sure, if that’s likely.<br />

**AS3364: This is a linear-control version of the AS2164<br />
Given the number of times the Gallo-Irwin circuit gets used to make a linear<br />
VCA out of the 2164, this is an excellent idea. Now you get four of them on<br />
one chip (instead of two linearised VCAs per 2164) without needing the extra<br />
op-amps. Fantastic idea. Having the option of linear or log control by<br />
choosing the chip you need is great.**<br />
<br />
I'm excited about this. I just wonder a) how well it shuts off at 0V CV,<br />
and b) whether it gets noticeably warm when all the VCAs are off (which the<br />
Irwin circuits will do if you don't add a current limiting resistor).<br /></blockquote>
