TDA7563A:Intelligent high efficiency (class SB) quad BTL output with full I2C diagnostics (turn on, permanent, ac) and stand-by/mute input

The TDA7563A is a new BCD technology Quad Bridge type of car radio amplifier in Flexiwatt27 & PowerSO36 packages specially intended for car radio applications.

Thanks to the DMOS output stage the TDA7563A 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 I2C bus.
