Arduino controlled Dual Mono AK4490 DAC (part 3)

Arduino controlled Dual Mono AK4490 DAC

Here’s the part 3 of Dimitris’ Arduino controlled Dual Mono AK4490 DAC project we covered previously:

Following up on Part 2, it’s time to talk about the output stage.
This output stage is the brainchild of my friend Kostas, all I did was lay out the PCB.
It is a fully discreet single-ended class-A output stage, outputting ~2.4V RMS.

More details on Dimdim’s blog. If you missed part 1 and part 2, be sure to check it out.
