DESCRIPTION
The TDA7564 is a new BCD technology QUAD
BRIDGE type of car radio amplifier in Flexiwatt25
package specially intended for car radio applica-

tions. 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 de-
vice to simplify the thermal management in high
power sets.The dissipated output power under av-
erage listening condition is in fact reduced up to
50% when compared to the level provided by con-
ventional class AB solutions.This device is
equipped with a full diagnostics array that commu-
nicates the status of each speaker through the I

C
bus.The possibility to control the configuration and
behaviour of the device by means of the I
2
C bus
makes TDA7564 a very flexible machine.
