Description

The TDA7563B 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 TDA7563B

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.
