DESCRIPTION
The TDA7296S 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-
MULTIPOWER BCD TECHNOLOGY
Multiwatt15
ORDERING NUMBER: TDA7296SV
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 4Ω and 8Ω 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.
