And the answer: eeeeh sort of. Most affordable in small quantities that I can find is the Intersil HI1178, but all these parts give off big "last orders please, we're shutting down the line" vibes. Except for the Analog parts, but unless you're buying reels of 2500, the one DAC would end up being a large chunk of the BOM cost...
It's annoying because I don't love the yolo-ness of the resistor DAC from a robustness POV... but it's quite hard to beat "about 1 cent in medium quantity".
