Note 1: The nonlinearity error refers to a deviation from ideal conversion characteristics after the offset/
full-scale errors have been adjusted to 0. When AVCC = VREF = 5.12 V, 1 LSB = 5 mV.
Note 2: This refers to input leakage current on AN0-AN15 when the A-D converter remains idle.
Input voltage condition: 0
