(1) The leakage current is specified by the digital I/O input leakage.
(2) The analog input voltage range must be within the selected reference voltage range V_R+ to V_R– for valid conversion results. If the
reference voltage is supplied by an external source or if the internal reference voltage is used and REFOUT = 1, then decoupling
capacitors are required. See REF, External Reference and REF, Built-In Reference.
(3) The internal reference supply current is not included in current consumption parameter I_{ADC12_A}.

(3) Approximately ten Tau (t) are needed to get an error of less than ±0.5 LSB:
t_Sample = ln(2ⁿ⁺¹) x (R_S + R_I) × C_I + 800 ns, where n = ADC resolution = 12, R_S = external source resistance
