Note 1: The absolute accuracy indicates the accuracy of output codes produced by the A-D
converter with respect to analog inputs including all error sources (e.g., quantization and
other errors), and is calculated by the equation below.
Absolute accuracy = output code - (analog input voltage Ni / 1 LSB)
where 1 LSB = 5 mV when AVCC = VREF = 5.12 V
Note 2: This refers to the input leakage current on AN0-AN15 when the A-D converter is inactive.
Input voltage conditions are 0 ANi AVCC. Temperature conditions are Ta =-40 to 85
°
C.
