The number of A/D converter digital conversion output codes
The deviation of the actual A/D conversion characteristic from the ideal A/D conversion
characteristic when the digital output value changes from the minimum voltage value (zero
voltage) B'000000000000 to B'000000000001. Does not include a quantization error (see
figure 17.8).
The deviation of the actual A/D conversion characteristic from the ideal A/D conversion
characteristic when the digital output value changes from B'111111111110 to the maximum
voltage value (full-scale voltage) B'111111111111. Does not include a quantization error (see
figure 17.8).
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 17.8).
The deviation of the actual A/D conversion characteristic from 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 17.8).
The deviation between the digital value and the analog input value. Includes offset error, full-
scale error, quantization error, and nonlinearity error.
