DESCRIPTION
The TDA7296A 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 4Ω and 8Ω loads

ORDERING NUMBER: TDA7296AV
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.
The device provides a circuit for the detection of
clipping in the output stages. The output, on open
collector, is able to drive system with automatic
level control.
