So here I go again with the ever-more-difficult-and-more-expensive projects. This time I wanted to try out a DAC that doesn't get much exposure around here since you really need a microcontroller to set it up properly - the AD1955. On paper, it's very competitive with PCM1794 and I'd like to give an active I/V a try - everything I have is either voltage out or passive I/V. In my continuing quest for ever-smaller boards, I've managed a layout in only 1.5"x2.5", which wasn't easy. That will make the build fun though, an average of 26 components per square inch in that space on both sides of the board.
Before I go ahead and send the design off for fabrication, I'm asking you folks to proofread my schematic and make any comments. It's pretty much lifted straight from the AD1955 datasheet with some simple changes. Anyone interested?
Here's the schematic. Please check out the PDF since it's too large to be readable at forum-size.
