(3) Notes on Using A/D Converter
<About the output impedance of the analog input of external circuit>
External impedance values of the external input of 4.2 k
Ω or lower (sampling period =1.2 μs@machine clock of
16 MHz) are recommended.
When the external impedance is too high, the sampling period 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.
