A method for minimizing the impact of stress conditions on the QADC64E is to strategically allocate
QADC64E 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.
