(4) A/D Converter Terms and Definitions
Resolution
The level of analog variation that can be distinguished by the A/D converter.
Linear error (unit : LSB)
The deviation between the value along a straight line connecting the zero transition point
(“00 0000 0000”
←→“00 0000 0001”) of a device and the full-scale transition point
(“11 1111 1110”
←→“11 1111 1111”) , compared with the actual conversion values obtained.
Differential linear error (Unit : LSB)
The deviation from the theoretical input voltage required to produce a change of 1 LSB in output code.
Total error (Unit : LSB)
The difference between theoretical conversion value and actual conversion value.
