TDA7563BPDTR

TDA7563BPDTR is a 4 x 50W multifunction quad power amplifier with built-in diagnostics feature. It has very low distortion allowing a clear powerful sound. Among the 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 upto 50% when compared to the level provided by conventional class AB solutions. This device is equipped with a full diagnostics array that communicates the status of each speaker through the I²C bus.
