filter capacitors like the ones in figure 15.7 are connected, the voltage values input to the
analog input pins (AN
occur if A/D conversion is frequently performed in scan mode so that the current that charges
and discharges the capacitor in the sample-and-hold circuit of the A/D converter becomes
greater than that input to the analog input pins via input impedance Rin. The circuit constants
should therefore be selected carefully.
