The number of A/D converter digital output codes
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 15.4).
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 (H'000) to
B'0000000001 (H'001) (see figure 15.5).
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from B'1111111110 (H'3FE) to B'1111111111 (H'3FF) (see
figure 15.5).
The error with respect to the ideal A/D conversion characteristic between zero voltage and full-
scale voltage. Does not include offset error, full-scale error, or quantization error (see figure
15.5).
The deviation between the digital value and the analog input value. Includes offset error, full-
scale error, quantization error, and nonlinearity error.
