IIAN Analog Input Leakage Current (Note 2) AVSS≤ANi≤AVCC -5 5 µA
Note 1: Absolute accuracy refers to the accuracy of output code relative to the analog input including all error sources
(including quantization error) in an A-D converter, and is calculated using the equation below.
Absolute accuracy = output code – (analog input voltage Ani / 1 LSB)
When AVCC = AVREF = 5.12 V, 1 LSB = 5 mV.
Note 2: This refers to the input leakage current on ANi while the A-D converter remains idle.
