(1)

The TPA3007D1 must not be used with any speaker or load (including speaker with output filter) that could vary below 7.0

Ω 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.
