Here’s the part 3 of Dimitris’ Arduino controlled Dual Mono AK4490 DAC project. If you missed part 1 and part 2, check them out.

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.
