(2) Notes on Using A/D Converter <About the output impedance of the analog input of external circuit> When the external impedance is too high, the sampling time for analog voltages may not be sufficient. In this case, it is recommended to connect the capacitor (approx. 0.1 µF) to the analog input pin. − Analog input circuit model R C 12bit A/D 3.0kΩ (max) 8.30pF (max) (4.5V ≤ AVcc ≤ 5.5V) Note: Listed values must be considered as reference values.
