i haven't posted a circuit doodle in quite a while, have some bedtime ADC fun :D

the internal reference in this part seems to be pretty accurate, so i won't play around with an external one.

my goal with this is to build a small board for common sensing needs which doesn't cost too much and i can just put wherever i need.

also gonna build a small multimeter i can plug into prototype setups. no more awkwardly probing all the things one after another ^^

@ln You can add multiplexers, that's how I built a 32 channel multimeter (I think with the same IC).

@ln I don't remember, some random analog mux which my local Conrad had.
