Notes:
(*) The values are expected at 25 Celsius degrees with
(**)’LSBs’ , as used here, as a value of
(1) @ 24 MHz external clock
(2) including Sample time
(3) it must be considered as the on-chip series resistance before the sampling capacitor
(4) DNL ERROR= max {[V(i) -V(i-1)] / LSB-1}INL ERROR= max {[V(i) -V(0)] / LSB-i}
ABSOLUTE ACCURACY= overall max conversion error
