Got a mini adapter board designed and ordered for the Cirrus Logic WM8524CGEDT I2S Stereo Audio DAC. 24-bit, 106dB SNR. Dual RCA line-level outputs, which are also available on the pin header.

BTW, this DAC runs directly on a single 3v3 supply. It has a built-in charge pump and bias servo to output true 2V line-level signals without using external coupling capacitors. This also eliminates the "pops" commonly encountered when these devices are powered on or off. Cool! :)

Eagle 7.5 files for this audio DAC board are available in the project files section.
