I've got a couple of projects in mind that require control of resistance, so I started looking at interfacing a digital pot to the arduino. Of course, I was happy to find the "Controlling a Digital Potentiometer Using SPI" article here on arduino.cc. It -- and a few other articles I found -- seem to prefer the AD5206 or 04 chip...but for the life of me I can't find anywhere I can buy one.
I buy a fair bit from places like sparkfun, vetco, or even the local radio shack. But no one seems to have the 5206 -- at least not if I don't want to order a lot of 100 of them :)
Has anyone had any luck finding them online? I just need 2 or 3 of them (to start, at least).
Thanks for your help,
