Hi folks, noob here :) I'm trying to build an audio-filterbox based around the ssm2044 filter IC from the 80s and an Arduino Due. This site:
which shows example circuits involving said IC, shows that you need 15V (and -15V?) to operate it. My first research revealed that I'd need a voltage regulator like a 7805 to get it. To what do I connect these? do I need another PSU? (I have USB and a 12V 2A PSU).
Also I found some information on a similar project, which said I could control the resonance and filtercutoff via digital potentiometers. What would be a good choice here if the stepping of the digi-poti should be at least 256 steps?
Any help appreciated! :) Thanks, Fred
