Section 20 A/D Converter (ADC)
20.6
The A/D converter compares an analog value input from an analog input channel with its analog
reference value and converts it to 10-bit digital data. The absolute accuracy of this A/D conversion
is the deviation between the input analog value and the output digital value. It includes the
following errors:
• Offset error
• Full-scale error
• Quantization error
• Nonlinearity error
These four error quantities are explained below with reference to figure 20.7. In the figure, the 10-
bit A/D converter is illustrated as the 3-bit A/D converter for explanation. Offset error is the
deviation between actual and ideal A/D conversion characteristics when the digital output value
changes from the minimum (zero voltage) B'0000000000 (000 in the figure) to B'000000001 (001
in the figure) (figure 20.7, item (1)). Full-scale error is the deviation between actual and ideal A/D
conversion characteristics when the digital output value changes from B'1111111110 (110 in the
figure) to the maximum B'1111111111 (111 in the figure) (figure 20.7, item (2)). Quantization
error is the intrinsic error of the A/D converter and is expressed as 1/2 LSB (figure 20.7, item (3)).
Nonlinearity error is the deviation between actual and ideal A/D conversion characteristics
between zero voltage and full-scale voltage (figure 20.7, item (4)). Note that it does not include
offset, full-scale, or quantization error.
