Notes:
The smaller the | AVRH – AVRL |, the greater the error would become relatively.
Use the output impedance of the external circuit for analog input under the following conditions:
External circuit output impedance < approx. 10 k

is caused by a noise to drop to below the analog input voltage, the analog input
current is likely to increase. In such cases, a bypass capacitor or the like should be provided in the external
circuit to suppress the noise.
