(3) Precautions
The smaller the | AVR–AV
SS
|, the greater the error would become relatively.
The output impedance of the external circuit for the analog input must satisfy the following conditions:
Output impedance of the external circuit < Approx. 10 k
If the output impedance of the external circuit is too high, an analog voltage sampling time might be
insufficient (sampling time = 6
μ
s at 10MHz oscillation.)
(4) A/D Converter Glossary
Resolution
Analog changes that are identifiable with the A/D converter.
Linearity error
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 1110”
“11 1111 1111”) from actual conversion characteristics
Differential linearity error
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 caused by the zero transition error, full-scale
transition error, linearity error, quantization error, and noise

If the analog input
impedance is higher
than 10 kW, it is
recommended to
connect an external
capacitor of approx.
0.1 mF.
