* :The current value applies to the CPU stop mode with the A/D converter inactive (V

= AVRH = +5.5 V).
Notes: (1) The smaller the | AVRH – AVRL |, the greater the error would become relatively.
(2) Use the output impedance of the external circuit for analog input under the following conditions:
External circuit output impedance < approx. 10 k
(Sampling period
(3) Precision values are standard values applicable to sleep mode.
(4) If V

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.
