General description
Amplifier organization
The TDA7360 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, excellent electrical performances, flexibility in use, superior reliability thanks to a built-
in array of protections. As a result the following performances has been achieved:
Block description
Polarization
The device is organized with the gain resistors directly connected to the signal ground pin
i.e. without gain capacitors
The non inverting inputs of the amplifiers are connected to the SVR pin by means of resistor
dividers, equal to the feedback networks. This allows the outputs to track the SVR pin which
is sufficiently 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 CSVR, more than 60dB of ripple rejection can be obtained.
Delayed turn-on (muting)
The C
the voltage on SVR pin reaches ~2.5V typ
duplicating the input differential pair
an internal mute input. This feature is necessary to prevent transients at the inputs reaching
the loudspeaker(s) immediately after power-on).
Figure 1
At the power-on the output decoupling capacitors are charged through an internal path but
the device itself remains switched off (Phase 1 of the represented diagram).

SVR
represents the detailed turn-on transient with reference to the stereo configuration.
No need of bootstrap capacitors even at the highest output power levels
Absolute stability without external compensation thanks to the innovative out stage
configuration, also allowing internally fixed closed loop lower than competitors
Low gain (20 dB stereo fixed without any external components) in order to
minimize the output noise and optimize SVR
Silent Mute/Standby function featuring absence of pop ON/OFF noise
high SVR
Stereo/bridge operation without addition of external component
AC/DC short circuit protection (to GND, to V
Loudspeaker protection
Dump protection
ESD protection
sets a signal turn-on delay too. A circuit is included which mutes the device until
