(1) Stresses beyond those listed under “absolute maximum ratings”
may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any
other conditions beyond those indicated under “recommended
operating conditions” is not implied. Exposure to absolute-
maximum-rated conditions for extended periods may affect device
reliability.
(2) GREG is treated as an input when the GREG pin is overdriven by
GVDD of 12 V.

(1) The TAS5122 package is thermally enhanced for conductive
cooling using an exposed metal pad area. It is impractical to use the
device with the pad exposed to ambient air as the only heat sinking
of the device.
For this reason, RθJA a system parameter that characterizes the
thermal treatment provided in the application. An example and
discussion of typical system RθJA values are provided in the
Thermal Information section. This example provides additional
information regarding the power dissipation ratings. This example
should be used as a reference to calculate the heat dissipation
ratings for a specific application. TI application engineering
provides technical support to design heat sinks if needed.
