DESCRIPTION  
The TDA7454 is a new BCD technology QUAD  
BRIDGE type of car radio amplifier in Flexiwatt25  
packagespeciallyintendedforcarradioapplications.  
Among the features, its superior efficiency per-  
formance 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 conven-  
tional class AB solutions.
