20.6 A/D Conversion Accuracy Definitions
This LSI's A/D conversion accuracy definitions are given below.
• Resolution
The number of A/D converter digital output codes
• Quantization error
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 20.6).
• 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 0000000000 to 0000000001
(see figure 20.7).
• Full-scale error
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from 1111111110 to 1111111111 (see figure 20.7).
• Nonlinearity error
The error with respect to the ideal A/D conversion characteristics between zero voltage and
full-scale voltage. Does not include offset error, full-scale error, or quantization error.
• Absolute accuracy
The deviation between the digital value and the analog input value. Includes offset error, full-
scale error, quantization error, and nonlinearity error.
