Thanks to the DMOS output stage the TDA7564 has a 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 up to 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 I 2C bus.The possibility to control the configuration and behaviour of the device by means ...
