DESCRIPTION
The TDA7295 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
to the high out current capability it is able to sup-
ply the highest power into both 4
and 8 loads
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.
