(8) Definition of A-D Conversion Accuracy
The definition of A-D conversion accuracy is described below.
1Relative accuracy
Zero transition error (V0T)
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 VREF.
Non-linearity error
The deviation of the actual A-D conversion characteristics, from the
ideal A-D conversion characteristics between V0 and V254.
(V0 –1/2 ! VREF/256)
1LSB
V0T =
(VREF – 3/2 ! VREF/256) – V254

Non-linearity error =
[LSB]
Differential non-linearity error
The deviation of the input voltage required to change output data
by “1,” from the corresponding ideal A-D conversion characteris-
tics between 0 and VREF.
2Absolute accuracy
Absolute accuracy error
The deviation of the actual A-D conversion characteristics, from the
ideal A-D conversion characteristics between 0 and VREF.
Vn – (1LSB ! n + V0)

Differential non-linearity error =
(Vn+1 – Vn) – 1LSB

Absolute accuracy error =
1LSBA with respect to absolute accuracy =
1LSB with respect to relative accuracy =
Note: The analog input voltage “Vn” at which A-D conversion output
data changes from “n” to “n + 1” (n ; 0 to 254) is as follows
(refer to Figure 18).

Full-scale transition error (VFST)
The deviation of the input voltage at which A-D conversion output
data changes from “255” to “254,” from the corresponding ideal A-
D conversion characteristics between 0 and VREF.
