Key Features

  • its superior efficiency performance coming from the internal exclusive structure, makes it the most suitable device to simplify the thermal management in high power sets. The dissipated output power under average listening condition is in fact reduced up to 50% when compared to the level provided by conventional class AB solutions. This device is equipped with a full diagnostic array that communicates the status of each speaker through the I 2C bus. The TDA7575 has also the possibility of drivin.
