the 2.5V ref. is provided for possible more exact v. of this -- for example -- forward normalizing the output as Uout=Uin*Vref/(Vsup/2)
Comparative ref. test
Experimental /// Alternative (the best) /// Datasheet (the 2-nd best)
it seems that the inverter/comparator type ADC ↓↓ is the fastest here
now with CMOS-Comparators ((i tiled it up intuitively -- a top-down design -- surprisingly or not it came out the same as at the linked one ↑above↑))
(the chosen resistor values may be not the optimal or not the realistic 1-s)
