The absolute maximum ratings are determined over complete temperature range using corner
lots. The values are provided in Table 5.

Temperature measured by the internal temperature sensor. This temperature value depends
on the PCB temperature, sensor element self-heating and ambient temperature and is typically
above ambient temperature.
