6. A/D Glossary
Resolution
Analog changes that are identiable with the A/D converter
Linearity error
The deviation of the straight line connecting the zero transition point (“0000 0000”
“0000 0001”) with the
full-scale transition point (“1111 1111”
“1111 1110”) 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
The difference between actual and theoretical value
This error is caused by the zero transition error, full-scale transition error, linearity error, quantization error,
and noise.
