A/D Conversion Precision Definitions: H8S/2357 Group A/D conversion precision definitions are given below.
Rev.6.00 Oct.28.2004 page 552 of 1016
REJ09B0138-0600H
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'000) to B'0000000001 (H'001) (see figure 16-9).
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'3FE) to B'1111111111 (H'3FF) (see figure 16-9).
Quantization error
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 16-8).
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.
