Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 7:
Zero-scale error is the offset voltage measured from 0.5LSB may cause permanent damage to the device. Exposure to any Absolute when the output code flickers between 0000 0000 0000 0000 and Maximum Rating condition for extended periods may effect device 0000 0000 0000 0001. Full-scale error is the deviation of the last code reliability and lifetime. transition from ideal and includes the effect of offset error.
