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.

The TPA3007D1 must not be used with any speaker or load (including speaker with output filter) that could vary below 7.0
over the
audio frequency band.
(2)
Continuous operation above the recommended junction temperature may result in reduced reliability and/or lifetime of the device. The
junction temperature is controlled by the thermal design of the application and should be carefully considered in high power dissipation
applications. See the thermal considerations section on page 14 for recommendations on improving the thermal performance of your
application.
