1) Not subjected to production test, verified by design/characterization
2) TUE is tested at
V
AREF =5.0 V, VAGND =0V, VDDP =5.0 V.
3) An overload current (
I
OV) through a pin injects a certain error current (IINJ) into the adjacent pins. This error
current adds to the respective pin’s leakage current (
I
OZ). The amount of error current depends on the overload
current and is defined by the overload coupling factor
K
OV. The polarity of the injected error current is inverse
compared to the polarity of the overload current that produces it. The total current through a pin is |
I
TOT| = |IOZ1|
+ (|
I
OV| × KOV). The additional error current may distort the input voltage on analog inputs.
4) This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage
at once. Instead of this, smaller capacitances are successively switched to the reference voltage.
5) The sampling capacity of the conversion C-Network is pre-charged to
V
AREF/2 before connecting the input to
the C-Network. Because of the parasitic elements, the voltage measured at ANx is lower than
V
AREF/2.
