15.6 Definition of A/D Converter Terms

(Continued)

Resolution

: Analog variation that is recognized by an A/D converter.

Non 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

linearity error

: Deviation of input voltage, which is required for changing output code by 1 LSB, from an ideal value.

Total error

Difference between an actual value and a theoretical value. A total error includes zero transition error,

full-scale transition error, and linear error.
