The real test will come when you check the drift on the part.
Some of these are pretty much zero drift, but some are not. The part looks pretty much the same as it has been for decades, and it still goes through the magic marker process. The board says, "Made in Malaysia", so it is going to use the same production parts as the previous version.
I'd tag the whole board at somewhere in September 2019 (week 42).
Now - what did they do to replace that Elantec super high speed comparator? Looks like they might have used this part TL3016 - except it took 3 parts to replace one Elantec 3016. The TI is faster, but has higher offset currents.
Hmph - the TI part is 5V only, so it needs regulators, which is what the other parts look like. I still wonder if the TI part might offer better performance, although it seems unlikely from the spec.
So there's an exercise to figure out why the black version has three of these in place of one elantec - making it equivalent in performance, or making it better? I'd assume that better performance results in less noise in the ADC which would be interesting.
If we could get a sharper picture of the bottom left corner of the board, that would be really helpful. I can't quite figure out what those other parts are. I thought they might also be 3016s, but the wiring is odd.
