• Analog input circuit model
Use the device with external circuits of the following output impedance for analog inputs :

Note : Use the values in the figure only as a guideline.
• Recommended output impedance of external circuits are : Approx. 1.5 kΩ or lower (4.0 V ≤ AV
• If an external capacitor is used, in consideration of the effect by tap capacitance caused by external capacitors
• If output impedance of an external circuit is too high, a sampling period for an analog voltage may be
and on-chip capacitors, capacitance of the external one is recommended to be several thousand times as
high as internal capacitor.
