Well, I managed to destroy my prototype board in the process of fiddling with it. I did get another strung together version to work, but I've desided to just throw out the design I was using (eval board active filter) in favor of one designed from scratch. This new design SHOULD work better. Anyone wanting to build their own, just download the CS4334 eval board from Crystal's website, If you want to get 4 volts P-P you will have to modify the circuit, but that is up to you. Otherwise just wait for me to finish .

New design will have a more solid ground plain, better components and better design. It shouldn't take long to finish. MAYBE later this week.
