Notes on Using A/D Converter
Select the output impedance value for the external circuit of analog input according to the following conditions, :
Output impedance values of the external circuit of 15 k
or lower are recommended.
When capacitors are connected to external pins, the capacitance of several thousand times the internal
capacitor value is recommended to minimized the effect of voltage distribution between the external capacitor
and internal capacitor.
When the output impedance of the external circuit is too high, the sampling period for analog voltages may not
be sufficient (sampling period = 4.00
μ
s @machine clock of 16 MHz).
