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 10oC.

16) Applies to AINx, when used as auxiliary reference inputs.
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) RAIN7T = 1400 Ohm maximum and 830 Ohm typical in the
20) The DC current at the pin is limited to 3 mA for the operational lifetime.
