7. A/D Converter Glossary
• Resolution
• Linearity error
• Differential linearity error
• Total error
The smallest change in analog voltage detected by A/D converter.
A deviation of actual conversion characteristic from a line connecting the zero-traction point (between “00 0000
0000” ↔ “00 0000 0001”) to the full-scale transition point (between “11 1111 1110” ↔ “11 1111 1111”) .
A deviation of a step voltage for changing the LSB of output code from ideal input voltage.
A difference between actual value and theoretical value. The overall error includes zero-transition error, full-
scale transition error and linearity error.
