Section 19 A/D Converter (ADC)
Offset error is the deviation between actual and ideal A/D conversion characteristics when the
digital output value changes from the minimum (zero voltage) 0000000000 (000 in the figure) to
000000001 (001 in the figure) (figure 19.10, item (1)). Full-scale error is the deviation between
actual and ideal A/D conversion characteristics when the digital output value changes from the
1111111110 (110 in the figure) to the maximum 1111111111 (111 in the figure) (figure 19.10,
item (2)). Quantization error is the intrinsic error of the A/D converter and is expressed as 1/2 LSB
(figure 19.10, item (3)). Nonlinearity error is the deviation between actual and ideal A/D
conversion characteristics between zero voltage and full-scale voltage (figure 19.10, item (4)).
Note that it does not include offset, full-scale or quantization error.
