(2) Definitions of Terms
Resolution: Analog transition identifiable by the A/D converter.
Analog voltage can be divided into 1024 (210) components at 10-bit resolution.
Total error: Difference between actual and logical values. This error is the sum of an offset error, gain error,
non-linearity error and an error caused by noise.
Linearity error: Deviation of the straight line drawn between the zero transition point (00 0000 0000 <-> 00
0000 0001) and the full-scale transition point (11 1111 1110 <-> 11 1111 1111) of the device
from actual conversion characteristics
Differential linearity error: Deviation from the ideal input voltage required to shift output code by one LSB
