(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) The duration of voltage spike should be less than 100 ns; see
application note SLEA025.
(3) GREG is treated as an input when the GREG pin is overdriven by
GVDD of 12 V.

(4) The TAS5112A 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, is provided in the Application Information section
of the data sheet. 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
heatsinks if needed.
