38.6
The A/D converter compares an input for an analog channel to its analog reference voltage and
converts it into 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:
1. Offset error (figure 38.5 (1))
2. Full-scale error (figure 38.5 (2))
3. Quantization error (figure 38.5 (3))
4. Nonlinearity error (figure 38.5 (4))
Deviation between actual A/D conversion characteristics and ideal A/D conversion
characteristics when the digital output value changes from the minimum (zero voltage)
0000000000 (000 in figure 38.5) to 0000000001 (001 in figure 38.5)
Deviation between actual A/D conversion characteristics and ideal A/D conversion
characteristics when the digital output value changes from 1111111110 (110 in figure 38.5) to
the maximum 1111111111 (111 in figure 38.5).
Intrinsic error of the A/D converter and is expressed as 1/2 LSB.
Deviation between actual A/D conversion characteristics and ideal A/D conversion
characteristics between zero voltage and full-scale voltage. Note that it does not include offset,
full-scale, and quantization errors.
