12) Only one of these parameters is tested, the other is verified by design characterization.
13) The leakage current decreases typically 30% for junction temperature decrease of 10
14) Applies to AINx, when used as auxiliary reference inputs.

16) For the definition of the parameters see also
17) This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage
18) The sampling capacity of the conversion C-Network is pre-charged to
19)
20) The DC current at the pin is limited to 3 mA for the operational lifetime.

All ADC conversions with a duration longer than
at once. Instead of this smaller capacitances are successively switched to the reference voltage.
Because of the parasitic elements the voltage measured at AINx can deviate from
1.35V.
