DESCRIPTION
The TDA7360isa new technology class AB
Audio Power Amplifierin the Multiwatt package
designedfor car radio applications.
Thanksto the fully complementary PNP/NPN out-
put configuration the high power performanceof
the TDA7360is obtained without bootstrap ca-
pacitors. delayed turn-on mute circuit eliminates audible
on/off noise, anda novel short circuit protection
system prevents spurious intervention with highly
inductive loads.
The device providesa circuit for the detectionof
clippingin the output stages. The output,an open
collector,is ableto drive systems with automatic
volume control.

AMPLIFIER ORGANIZATION
The TDA7360 has been developed taking careof
the key conceptsof the modern power audio am-
plifier for car radio such as: space and costs sav-
ing dueto the minimized external count, excellent
electrical performances, flexibilityin use, superior
reliability thankstoa built-in arrayof protections.a result the following performances has been
achieved: NEED OF BOOTSTRAP CAPACITORS
EVEN AT THE HIGHEST OUTPUT POWER

BLOCK DESCRIPTION
Polarization
The deviceis organized with the gain resistorsdi-
rectly connectedto the signal ground pin i.e. with-
out gain capacitors (fig. 23).
The non inverting inputsof the amplifiers are con-
nectedto the SVR pinby meansof resistor divid-
ers, equalto the feedback networks. This allows
the outputsto track the SVR pin whichis suffi-
ciently slowto avoid audible turn-on and turn-off
transients.
SVR
The voltage rippleon the outputsis equalto the
one on SVR pin: with appropriate selectionof
CSVR, more than 60dBof ripple rejection can be
obtained.
Delayed Turn-on (muting)
The CSVR setsa signal turn-on delay too.A circuit included which mutes the device until the volt-
ageon SVR pin reaches ~2.5V typ. (fig. 25). The
mute functionis obtainedby duplicating the input
differential pair (fig. 24):it canbe switchedto the
signal sourceorto an internal mute input. This
featureis necessaryto prevent transientsat the
inputs reaching the loudspeaker(s) immediately
after power-on).
Fig. 25 represents the detailed turn-on transient
with referenceto the stereo configuration. the power-on the output decoupling capacitors
are charged through an internal path but the de-
vice itself remains switched off (phase1of the
represented diagram).
When the outputs reach the voltage levelof about (this means that thereisno presenceof short
circuits) the device switches on, the SVR capaci-
tor starts charging itself and the output tracks ex-
actly the SVRpin.
During this phase the deviceis muted until the
SVR reaches the ”Play” threshold (~2.5V typ.), af-
ter that the music signal starts being played.

Stereo/Bridge Switching
Thereis alsono need for external componentsfor
changing from stereoto bridge configuration (figg.
23-26).A simpleshort circuit between two pinsal-
lows phase reversalat one output, yet maintain-
ing the quiescent output voltage.
Stand-by
The deviceis also equipped witha stand-by func-
tion, so thata low current, and hence low cost
switch, canbe used for turn on/off.
Stability
The deviceis provided with an internal compen-
sation wich allowsto reach low valuesof closed
loop gain. this way better performanceson S/N ratio and
SVR canbe obtained.
