A/D ANALOG SPECIFICATIONS
(V
Note:
(1) “1LSBideal” has a value of AV
(2) Including sample time
(3) This is the internal series resistance before the sampling capacitor
(4) This is a typical expected value, but not a tested production parameter.
(5) Simulated value.
(6) The specified values are guaranteed only if an overload condition occurs on a maximum of 2 non-selected analog input pins and the

OFFSET ERROR= deviation between the actual V(0) and the ideal V(0) (=1/2 LSB)
GAIN ERROR= deviation between the actual V(254) and the ideal V(254) - V(0) (ideal V(254)=AV
DNL ERROR= max {[V(i) - V(i-1)]/LSB - 1}
INL ERROR= max {[V(i) - V(0)]/LSB - i}
ABS. ACCURACY= overall max conversion error
