DESCRIPTION
The TDA7563 is a new BCD technology Quad Bridge type of car radio amplifier in Flexiwatt27 package specially intended for car radio applica tions. Thanks to the DMOS output stage the TDA7563 has a very low distortion allowing a clear powerful sound. Among the features, its superior efficiency performance coming from the internal ex clusive 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 conven tional class AB solutions.This device is equipped with a full diagnostics array that communicates the status of each speaker through the I2C bus.
