I always wanted to build PCM2702 USB DAC also known as Guzzler’s DAC. I contacted Guzzler but he was completely out of boards. I realized that the only chance for me to build the DAC is to order the boards myself. Guzzler has kindly sent me his Eagle files and has been very supportive. The original design did not fit my needs 100%. So presented with the opportunity, I took the liberty of making some minor modifications to the board layout and to the schematic.
The new schematic
The new board layout
The changes:
* New board size 50.5mm x 57mm. The board now fits Hammond 1455C802.
* Mounting holes in each corner.
* Prominent USB connector (3.2 mm) for easier panel mounting.
* An option to power the DAC directly from MINT/PIMETA.
* All resistors are 1206.
* No R7 (it was not used anyway).
* Place for L2
* The schematic and the board are now consistent.
Your comments are very welcome!
