AMPLIFIER ORGANIZATION
The TDA7350A has been developed taking care
of the key concepts of the modern power audio
amplifier for car radio such as: space and costs
saving due to the minimized external count, ex-
cellent electrical performances, flexibility in use,
superiorreliability thanks to a built-in array of pro-
tections. As a result the following performances
has been achieved:
NO NEED OF BOOTSTRAP CAPACITORS
EVEN AT THE HIGHEST OUTPUT POWER
LEVELS
ABSOLUTE STABILITY WITHOUT EXTER-
NAL COMPENSATION THANKS TO THE IN-
NOVATIVE OUT STAGE CONFIGURATION,

BLOCK DESCRIPTION
Polarization
The device is organized with the gain resistors di-
rectly connected to the signal ground pin i.e.with-
outgain capacitors(fig. 24).
The non inverting inputs of the amplifiers are con-
nected to the SVR pin by means of resistor divid-
ers, equal to the feedback networks. This allows
the outputs to track the SVR pin which is suffi-
ciently slow to avoid audible turn-on and turn-off
transients.
SVR
The voltage ripple on the outputs is equal to the
one on SVR pin: with appropriate selection of
C
SVR
, more than 55dB of ripple rejection can be
obtained.
Delayed Turn-on (muting)
The C
SVR
sets a signal turn-on delay too. A circuit
is included which mutes the device until the volt-
age on SVR pin reaches ~2.5V typ (fig. 25). The
mute function is obtained by duplicating the input
differential pair (fig. 26): it can be switched to the
signal source or to an internal mute input. This
feature is necessary to prevent transients at the
inputs reaching the loudspeaker(s) immediately
