(8) Definition of A-D Conversion Accuracy
The definition of A-D conversion accuracy is described below.
Relative accuracy
Zero transition error (V
0T
)
The deviation of the input voltage at which A-D conversion output
data changes from “0” to “1,” from the corresponding ideal A-D
conversion characteristics between 0 and V
REF
.
Non-linearity error
The deviation of the actual A-D conversion characteristics, from the
ideal A-D conversion characteristics between V
0
and V
