A/D Conversion Precision Definitions: The chip's A/D conversion precision definitions are
given below.
• Resolution
The number of A/D converter digital output codes.
• Offset error
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from the minimum voltage value B'0000000000 to
B'0000000001 (see figure 14-9).
• Full-scale error
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from B'1111111110 to B'1111111111 (see figure 14-9).
