CC
= AVRH = 5.0 V)
Note:
The error increases proportionally as |AVRH - AVRL| decreases.
The output impedance of the external circuits connected to the analog inputs should be in the following
range.
The output impedance of the external circuit : 15.5 k
(Max) (Sampling time = 4.0
μ
s)
If the output impedance of the external circuit is too high, the sampling time might be insufficient.
