Description
The TDA7563B is a new BCD technology quad
bridge type of car radio amplifier in Flexiwatt27
package 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 I
2
C bus.
