2.3 Absolute Minimum and Maximum Ratings
Stress levels beyond those listed in Table 6 may cause permanent damage to the device or affect the reliability of the
sensor. These are stress ratings only and functional operation of the device at these conditions is not guaranteed. Ratings
are only tested each at a time.
