It is 12bit but the bottom 0-0.1v and 3.2v-3.3v just read as the min-max.

Honestly for many projects needing analog it might be "good enough", but it leaves a lot to be desired, and like the parent said, the moment you're looking for a a i2c adc you end up looking at another MCU anyway.

That's if you need an analog adc which my projects don't (sensors are all i2c anyway) but definitely takes away from being used as a general purpose chip.

It is a shame espressif didn't put a better adc in there.
