Fantasma25 Posted July 7, 2014 Report Share Posted July 7, 2014 Hello. I'm working on a MAX5556 Audio DAC Wing and I thought I should share it here . It (obviously) has a MAX5556 Stereo DAC at its core, with an I2S-compatible interface and up to 50KHz sampling rate (perfect for standard 44.1 and 48 KHz sampling rates) and a resolution of 16 and 24 bits. The board does not contain any output buffer as I wanted the board to be as small as possible. It only has the MAX5556, a couple of passives and a 3.5mm stereo jack. I'll leave you with the schematics and a render of the board. Any criticism is well accepted I'm also prototyping a Megawing with an ADC, a DAC and an Ethernet controller to stream audio over ethernet.

Jack Gassett Posted July 12, 2014 Report Share Posted July 12, 2014 Fantasma, That looks nice, what did you use to design it? Kicad? Jack. Link to comment Share on other sites More sharing options...
Fantasma25 Posted July 12, 2014 Author Report Share Posted July 12, 2014 Yep, I used Kicad. . I ordered some free samples of the chip, but the pcb has not arrived yet. I'll let you know how it went. Link to comment Share on other sites More sharing options...

Fantasma25 Posted July 13, 2014 Author Report Share Posted July 13, 2014 Which ethernet controller ? Alvie I'm first going to try with the Microchip ENC28J60 and see how it goes Link to comment Share on other sites More sharing options...
alvieboy Posted July 16, 2014 Report Share Posted July 16, 2014 So you will be using a controller with an embedded stack I was thinking you might be using a GMII or similar. Jack has a RGMII module but we were not able to write a controller yet for it. Link to comment Share on other sites More sharing options...
OmniTechnoMancer Posted July 18, 2014 Report Share Posted July 18, 2014 It's not really doing ethernet if you dont use just a PHY on the wing Link to comment Share on other sites More sharing options...
