Hi

I'm looking for a digital potentiometer similar to the AD5206, but has 8 channels of output available.

Does anyone know of one that is arduino controllable and doesn't cost a fortune? I'm not having much luck finding one at the moment.

Thanks

6 channels is quite a lot for a digipot, most are single, dual, or quad. Never seen an 8 and can't search one. Does size/connection count matter that much for your project that you need to shave off one or two packages?

Couldn't you use a pair of AD5204 together with a bit of simple logic which directs the commands to either chip A or chip B

Multiplexing. Of course. Thats the way to do it.

I'm new to this physical computing thing. No problems with the software, just the electronic side of things is quite confusing at the moment.
