[sdiy] Analog Computational Unit

[Ryan Williams]

I was looking at the analog devices site and I'm came across this IC.

AD538. It's a realtime analog computational unit with the transfer function:
Vout = Vy*(Vz/Vx)^m
Vy, Vz, and Vx are inputs and m is chosen with resistors. m can range from 1/5 to 5.

I thought this might make an interesting module but I'm not quite sure how to go about using it for audio.  I wonder if anyone has thought of building something similar? After looking around I found the MOTM wavewarper which seems to do exactly this. I wonder if it uses the same chip.

this IC costs about $35 but I figure if it sounds cool then it'd be worth it.
