Definition of A/D Converter Terms
(Continued)
Resolution
: Analog variation that is recognized by an A/D converter.
Linear error
: Deviation between a line across zero-transition line (“00 0000 00 0 0”
←→“00 0000 0001”)
and full-scale transition line (“11 1111 11 1 0”
←→ “11 1111 1111”) and actual conversion
characteristics.
Differential linear
error
: Deviation of input voltage, that is required for changing output code by 1 LSB, from an ideal
value.
Total error
: Difference between an actual value and an ideal value. A total error includes zero transition
error, full-scale transition error, and linear error.
