TDA7492PE 2X45W BTL D類音頻放大器

The TDA7492PE is a dual BTL class-D audio amplifier with single power supply designed for home audio applications. The device is housed in a 36-pin PowerSSO package with exposed pad down (EPD) to facilitate power dissipation through a properly designed PCB area underneath the TDA7492PE.
