8.8.8 Definition of A-D Conversion Accuracy
The definition of A-D conversion accuracy is described below (refer
to Figure 8.8.4).
Accuracy is shown the difference between measurement result out-
put code and output code which is expected for A-D conversion whose
specification is ideal by using LSB.
The analog input voltage in accuracy measurement is made to be a
middle point of input voltage width (=1 LSB) which outputs the code
in which the A-D converter with the ideal characteristics is identical.
For example, 1 LSB
’
s width is 20 mV at V
REF
= 5.12V.
0 mV, 20 mV, 40 mV and 60 mV are selected for analog input voltage.
A-D conversion accuracy is shown in Fig 8.8.4.
That the output code expected in the ideal A-D converter is

on the = ±2LSB absolute accuracy, when the analog input voltage is
100 mV.
And, zero error and scale error are contained for the absolute accu-
racy, and the quantization error is not contained.
