A/D Conversion Precision Definitions: H8S/2626 Group and H8S/2623 Group A/D conversion
precision definitions are given below.
Note: Values are reference values.
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 (H'00) to
B'0000000001 (H'01) (see figure 16.10).
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 (H'3E) to B'1111111111 (H'3F) (see
figure 16.10).
Quantization error
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 16.9).
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 the offset error, full-scale error, or quantization error.
Absolute precision
The deviation between the digital value and the analog input value. Includes the offset error,
full-scale error, quantization error, and nonlinearity error.
