Does the max A/D port current flows only to pin selected in analog bit?

Latest Updated:03/01/2005

Question:

(A/D Converter)  According to the datasheet and user's manual, maximum A/D port input current II(AD) is 5.0μA. Does this flow only to the pin selected in the analog input pin selection bit? Also, does this current flow to the selected pin at all times ? [2005/03/01]

Answer:

A/D port input current II(AD) only flows to the pin selected in the analog input pin selection bit. A fixed current does not flow at all times. Rather than a fixed current flowing at all times, the current varies according to the analog input voltage etc. to a standard maximum value of 5.0μA. When A/D conversion is not being performed, IIA current does not flow, but an input current appropriate for the port (IIH, IIL) does. (#104829)
