The current into (I

expressed by this equation:
Where:
A method for minimizing the impact of stress conditions on the QADC is
to strategically allocate QADC inputs so that the lower accuracy inputs
are adjacent to the inputs most likely to see stress conditions.
Also, suitable source impedances should be selected to meet design
goals and minimize the effect of stress conditions.
The source impedance of the analog signal to be measured and any
intermediate filtering should be considered whether external
multiplexing is used or not.
typical analog signal sources to one QADC analog input pin through a
separate multiplexer chip. Also, an example of an analog signal source
connected directly to a QADC analog input channel is displayed.
