Definition of A/D Converter Terms
Resolution
Analog variation that is recognized by an A/D converter.
The 10-bit can resolve analog voltage into 210
= 1024.
Total error
This shows the difference between the actual voltage and the ideal value and means a total of error because of
offset error, gain error, non-linearity error and noise.
Linearity error
Deviation between a line across zero-transition line (00 0000 0000
00 0000 0001) and full-scale transition line
(11 1111 1110
11 1111 1111) and actual conversion characteristics.
Differential linear error
Deviation of input voltage, which is required for changing output code by 1 LSB, from an ideal value.
