A/D Converter Block Electrical Characteristics
*1 : Peripheral clock
= 25 MHz
*2 : Current value for A/D converters not in operation, CPU stop mode (VCC
= AVCC = AVRH = 3.3 V)
Notes :
As the absolute value of | AVRH - AVRL | decreases, relative error increases.
Output impedance of external circuit of analog input under following conditions;
Output impedance of external circuit < 5 k
If output impedance of external circuit is too high, analog voltage sampling time may be too short for
accurate sampling.
(VCC
= AVCC = AVRH = 3.3 V, AVSS = 0.0 V, TA = 0 °C to + 70 °C)
