  I was just typing out my reply, but yours is much more detailed anyway, @OP this is the correct solution.

  I’m in no position to discourage you from building this, but this is a fsr greater project than you’re writing it to be. Send me a link to the git repo, so I can tag along and keep updated!

  Thanks for the detailed answer, that helps a lot for my understanding.

  The project sounds like a lot of work, especially for such a niche application. Do you have a crowd to support this (with time or money) or do you plan pay for this and sell it in the end?

• ⁨Comment⁩ on ⁨Building a USB-C DAC in as small a package as possible⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:

  It somehow feels like you put a lot of thought into this already and missed starting from the beginning in this post.

  What device do you want to have a USB-C DAC for? What’s the actual size limitations and what power do you want to draw that would need a heatsink? Do you have specs in mind, or is there a comparable project already available to look at?

  That’s actually a great video, no-ideal opamp characteristics have caused me a lot of headaches on multiple occasions in the past.

  A regular USB-C hub would be an idea, but may not work with regular chargers…

• ⁨Comment⁩ on ⁨safe?⁩ ⁨⁨10⁩ ⁨months⁩ ago⁩:

  Then this is not safe.

  The maximum charge voltage for a lithium cell is 4.2V while USB will provide 5V. It may work for a while, it may fail in a safe state or something gets hot and burns.
