[1] Stresses above the absolute maximum ratings may cause permanent damage to the device. Exposure to absolute maximum ratings
conditions for extended periods may affect device reliability.
[2] The maximum allowed ambient temperature T_amb depends on the assembly condition of the package and especially on the design of
the PCB. The application mounting must be done in such a way that the maximum junction temperature T_j(max) is never exceeded.

The thermal resistance depends strongly on the nature of the PCB used in the application
and on its design. The thermal resistance given in Table 67 corresponds to the value that
can be measured on a multilayer PCB (4 layers) as defined by EIA/JESD51-2. This value
is given for information only.
The junction temperature influences strongly the reliability of an IC. The PCB used in the
application contributes on a large part to the overall thermal characteristic. It must
therefore be designed to insure that the junction temperature of the IC never exceeds
T_j(max) = 125 °C at the maximum ambient temperature.
The IC has to be soldered to ground with its die-attached paddle. Plenty of vias are
recommended to remove the heat.
