(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 time = 1.2 μS@ machine clock of
16 MHz) are recommended. In this case, it is recommended to connect the capacitor (approx. 0.1
μF) to the
analog input pin.
When the external impedance is too high, the sampling time for analog voltages may not be sufficient.
