22.7
This LSI’s A/D conversion accuracy definitions are given below.
Resolution
The number of A/D converter digital output codes
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 22.4).
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'00_0000_0000 (H'000) to
B'00_0000_0001 (H'001) (see figure 22.5).
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from B'11_1111_1110 (H'3FE) to B'11_1111_1111 (H'3FF)
(see figure 22.5).
The error with respect to the ideal A/D conversion characteristics between the zero voltage and
the full-scale voltage. Does not include the offset error, full-scale error, or quantization error
(see figure 22.5).
The deviation between the digital value and the analog input value. Includes the offset error,
full-scale error, quantization error, and nonlinearity error.
