5. A/D Converter Electrical Characteristics
(AVCC = VCC = 3.5 V to 6.0 V, FC = 10 MHz, AVSS = VSS = 0.0 V, TA = –40
°C to +85°C)
6. Notes on Using A/D Converter
The smaller | AVR – AVSS |, 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
s at 10 MHz oscillation).
An analog input equivalent circuit is shown below.
