5. Note on Noise: To prevent damage from surges and other abnormal voltages at the analog
input pins (AN
like the one in figure 15.7 between AV
and V
capacitors like the ones in figure 15.7 are connected, the voltage values input to the analog
input pins (AN
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 R
therefore be selected carefully.
Notes: 1. Numeric values are approximate.
