15. A/D Converter
6. A/D Conversion Accuracy Definitions: A/D conversion accuracy in the H8/3006 and H8/3007
are defined as follows:
⎯ Resolution
Digital output code length of A/D converter
⎯ Offset error
Deviation from ideal A/D conversion characteristic of analog input voltage required to
raise digital output from minimum voltage value 0000000000 to 0000000001 (figure
15.10)
⎯ Full-scale error
Deviation from ideal A/D conversion characteristic of analog input voltage required to
raise digital output from 1111111110 to 1111111111 (figure 15.10)
⎯ Quantization error
Intrinsic error of the A/D converter; 1/2 LSB (figure 15.9)
⎯ Nonlinearity error
Deviation from ideal A/D conversion characteristic in range from zero volts to full scale,
exclusive of offset error, full-scale error, and quantization error.
⎯ Absolute accuracy
Deviation of digital value from analog input value, including offset error, full-scale error,
quantization error, and nonlinearity error.
