6. A/D Converter Glossary
Resolution
Analog changes that are identifiable with the A/D converter.
When the number of bits is 10, analog voltage can be divide into 2
10
.
Linearity error (unit: LSB)
The deviation of the straight line connecting the zero transition point (“00 0000 0000”
“00 0000 0001”) with
the full-scale transition point (“11 1111 1110”
“11 1111 1111”) from actual conversion characteristics
Differential linearity error
The deviation of input voltage needed to change the output code by 1 LSB from the theoretical value
Total error (unit: LSB)
The difference between theoretical and actual conversion values caused by the zero transition error, full-scale
transition error, non-linearity error, differential linearity error, and noise
