class TV). Thanks to the wide voltage range and
to the high out current capability it is able to sup-
ply the highest power into both 4 and 8 loads.
The built in muting function with turn on delay
simplifies the remote operation avoiding switching
on-off noises.
Parallel mode is made possible by connecting
more device through of pin11. High output power
can be delivered to very low impedance loads, so
optimizing the thermal dissipation of the system.

... The solution shown as a principle shematic by Fig3 represents the DMOS unity - gain output buffer of the TDA7296S. This large-signal, high-power buffer must be ca- pable of handling extremely high current and volt- age levels while maintaining acceptably low har- monic distortion and good behaviour over frequency response ...
