to the high out current capability it is able to sup-  
ply the highest power into both 4and 8loads  
even in presence of poor supply regulation, with  
high Supply Voltage Rejection.  
The built in muting function with turn on delay  
simplifies the remote operation avoiding switching  
on-off noises.  
DESCRIPTION  
The TDA7294 is a monolithic integrated circuit in  
Multiwatt15 package, intended for use as audio  
class AB amplifier in Hi-Fi field applications  
(Home Stereo, self powered loudspeakers, Top-  
class TV). Thanks to the wide voltage range and
