Nonlinearity error
The error with respect to the ideal A/D conversion characteristic between the zero voltage and
the full-scale voltage. Does not include offset error, full-scale error, or quantization error.
Absolute accuracy
The deviation between the digital value and the analog input value. Includes offset error, full-
scale error, quantization error, and nonlinearity error.
