(VDD= 5V +/-10%; TA= 0 to 70°C; unless otherwise specified)

Notes:(*)The values are expected at 25 Celsius degrees with

VDD= 5V

(**)’LSBs’ , as used here, as a value of

VDD/256

(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
