5. A/D Converter Electrical Characteristics
(AVCC = VCC = 3.5 V to 6.0 V, FCH = 10 MHz, AVSS = VSS = 0.0 V, TA = –40
°C to +85°C)
Precautions:
The smaller the | 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 10MHz oscillation.)
