A/D Converter
(1) A/D Converter Electrical Characteristics
(VCC
= 5.0 V ± 10%, AVSS = VSS = 0.0 V, Ta = 40 °C to +85 °C)
* For information on tinst, see “(4) Instruction Cycle” in “4. AC Characteristics.”
(2) A/D Converter Glossary
Resolution
Analog changes that are identifiable with the A/D converter
When the number of bits is 10, analog voltage can be divided into 210 = 1024.
Linearity error (unit: LSB)
The deviation of the straight line connecting the zero transition point (“00 0000 0000”
“00 0000 0001”) with
the full-scale transition point (“11 1111 1111”
“11 1111 1110”) from actual conversion characteristics
Differential linearity error (unit: LSB)
The deviation of input voltage needed to change the output code by 1 LSB from the theoretical value
Total error (unit: LSB)
The difference between theoretical and actual conversion values
