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 (TPA3004D2) incorporates an exposed PowerPAD on the underside of the chip. This acts as a heatsink and must be connected to
a thermally dissipating plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction temperature
that could permanently damage the device. See TI Technical Brief SLMA002 for more information about utilizing the PowerPAD
thermally enhanced package.
