REJ09B0302-0300
A/D conversion accuracy in the H8/3052BF is 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.
