The TDA7498 is a Class 100W+100W Class D audio amplifier. The IC chip is powered by a single power supply and is used primarily in home theaters and powered speakers. And the TDA7498 is equipped with an EPU hyper-threaded package with a bare heat-dissipating soldering plate facing up, which is superior to the same amplifier in terms of sound quality and performance.
