The number of A/D converter digital conversion output codes
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
0000000000 to 0000000001 (see figure 14.9).
The deviation of the analog input voltage value from the ideal A/D conversion
characteristic when the digital output changes from 1111111110 to 111111111 (see figure
14.9).
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 14.8).
The error with respect to the ideal A/D conversion characteristic between the zero voltage
and the full-scale voltage. Does not include the offset error, full-scale error, or quantization
error.
The deviation between the digital value and the analog input value. Includes the offset
error, full-scale error, quantization error, and nonlinearity error.
