1) The sampling capacity of the conversion C-network is pre-charged to
V
AREF/2 before the sampling moment.
Because of the parasitic elements the voltage measured at AINx can deviate from
V
AREF/2.
2) Applies to AINx, when used as auxiliary reference input.
3) This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage
at once. Instead smaller capacitances are successively switched to the reference voltage.
4) The sum of DNL/INL/GAIN/OFF errors does not exceed the related TUE total unadjusted error.
5) If the analog reference voltage range is below
V
DDM but still in the defined range of VDDM / 2 and VDDM is used,
then the ADC converter errors increase. If the reference voltage is reduced by the factor k (k<1),
TUE,DNL,INL,Gain, and Offset errors increase also by the factor 1/k.
6) If a reduced analog reference voltage between 1V and
V
DDM / 2 is used, then there are additonal decrease in
the ADC speed and accuracy.
7) For 10-bit conversions the error value must be multiplied with a factor 0.25.
8) For 8-bit conversions the error value must be multiplied with a factor 0.0625.

AREF_MAX is valid for the minimum specified conversion time. The current flowing during an ADC conversion
with a duration of up to
t
c = 25 μs can be calculated with the formula IAREF_MAX = QCONV/tc. Every conversion
needs a total charge of
Q
CONV = 150 pC from VAREF.
10) All ADC conversions with a duration longer than
t
c = 25μs consume an IAREF_MAX = 6μA.
