When A-D converter isn't working, how much input leakage current has?

Latest Updated:10/19/2004

Question:

How much input leakage current does the microcomputer have when its A-D converter is not operating?

Answer:

The table below shows the rated value of the analog input leakage current (IIAN).

Symbol Parameter Rated Value
Min. Typ. Max.
IIAN Analog input leakage current (Note 1) -5 micro-A   5 micro-A

Note 1: This is the input leakage current on ADiINj when the A-D converter remains idle.
Conditions: 0V <= ADiINj <= AVCC, Ta = -40 degree C to 85 degree C
