= AVRH = 5.5 V).
Notes: The error becomes larger as |AVRH–AVRL| becomes smaller.
Use the output impedance of the external circuit for analog input under the following conditions: External
circuit output impedance < Approx. 7 k
If the output impedance the external circuit is too high, the analog voltage sampling time may be insufficient.
(Sampling time = 3.0
