Building a DAC

ballsingtripp · 1st January 2009, 08:06 PM

Hello

I've built a few modular synths, headphone amps, and other relatively easy stuff over the past year, and now I'm feeling ambitious enough to build a D/A converter.

I have a very minimal amount of knowledge of how they work (in detail), but plenty of knowledge of their function (and digital audio in general).

I'll need s/pdif input, up to 24/96 conversion, and a headphone amp. I'll be using the s/pdif out of a Presonus Firebox with Live and Logic.

So, with soldering experience, lots of time, and a couple hundred bucks, where do I start?

My latest project - DAC + headphone amp

I think that might be too elaborate for a first DAC project..

I was thinking something more like this:

What do you think?

Assuming you can get the parts, that is as good a place as any to start but for something more recent and a little more complex try these.

The EZDAC is surprisingly easy to build (once you perfect your SMD skills, that is)

OK, the EZDAC is conceptually very easy to build....the execution requires patience, a steady hand, a very fine soldering iron tip, and a temperature controlled iron.

But hey, I built one, and that's saying something.
