I returned to DIY electronics in 2009 after a 20 year pause by building a few kits to get in shape. This blog is for me to keep track of my progress.

ezDAC

After power amps, speakers and a preamp I wanted to try my hand in digital sources and built a version of ezDAC. It is a fairly simple DAC with a CS8416 digital receiver, an AD1896 sampling rate converter, and a PCM1794A with a passive I/V converter for the DAC proper. Nothing fancy, but sounds as good as my DacMagic.

I used three separate 3VA toroidal transformers (for digital circuits, the DAC, and opamps) in the PSU. The enclosure is from modushop. I had to re-create ezDAC's PCB using the free version of Eagle (which I had never used before) and learn to solder SMDs.
