2.7.13 Absolute Accuracy and Differential Non-Linearity Error
• Absolute accuracy
Absolute accuracy is the difference between output code based on the theoretical A-D conversion
characteristics, and actual A-D conversion result. When measuring absolute accuracy, the voltage at
the middle point of the width of analog input voltage (1-LSB width), that can meet the expectation of
outputting an equal code based on the theoretical A-D conversion characteristics, is used as an ana-
log input voltage. For example, if 10-bit resolution is used and if V
then 1-LSB width becomes 5 mV, and 0 mV, 5 mV, 10 mV, 15 mV, 20 mV, ···· are used as analog input
voltages. If analog input voltage is 25 mV, “absolute accuracy =
A-D conversion falls on a range from “002
pected from the theoretical A-D conversion characteristics. Zero error and full-scale error are included
in absolute accuracy.
