Thanks to the fully complementary PNP/NPN out-

put configuration the high power performance of

the TDA7360 is obtained without bootstrap ca-

pacitors.

A delayed turn-on mute circuit eliminates audible

on/off noise, and a novel short circuit protection

system prevents spurious intervention with highly

inductive loads.

The device provides a circuit for the detection of

clipping in the output stages. The output, an open

collector, is able to drive systems with automatic

volume control.

BLOCK DESCRIPTION

Polarization

The device is organized with the gain resistors di-

rectly connected to the signal ground pin i.e. with-

out gain capacitors(fig. 23).

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.

Figure 22: Power Dissipation & Efficiency vs.

OutputPower (Bridge)

SVR

The voltage ripple on the outputs is equal to the

one on SVR pin: with appropriate selection of

C_SVR, more than 60dB of ripple rejection can be

obtained.

Delayed Turn-on (muting)

The C_SVRsets 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. 24): 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

after power-on).

Fig. 25 represents the detailed turn-on transient

with reference to the stereo configuration.

At the power-on the output decoupling capacitors

are charged through an internal path but the de-

vice itself remains switched off (phase 1 of the

represented diagram).

When the outputs reach the voltage level of about

1V (this means that there is no presence of 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 device is muted until the

SVR reaches the ”Play” threshold (~2.5V typ.), af-

ter that the music signal starts being played.

AMPLIFIER ORGANIZATION

The TDA7360 has been developed taking care of

the key concepts of the modern power audio am-

plifier for car radio such as: space and costs sav-

ing 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:

tion, so that a low current, and hence low cost

switch, can be used for turn on/off.

Stereo/Bridge Switching

There is also no need for external componentsfor

changing from stereo to bridge configuration(figg.

23-26). A simple short circuit between two pins al-

lows phase reversal at one output, yet maintain-

ing the quiescent output voltage.

Stability

The device is provided with an internal compen-

sation wich allows to reach low values of closed

loop gain.

In this way better performances on S/N ratio and

SVR can be obtained.

Stand-by

The device is also equipped with a stand-by func-

out. (pin2) when a certain distortion level is

reached at each output. This particular function

allows compression facility whenever the amplifier

is overdriven, so obtaining high quality sound at

all listening levels.

CLIP DETECTOR

The TDA7360 is equipped with an internal circuit

able to detect the output stage saturation provid-

ing a proper current sinking into an open collector

OUTPUT STAGE

Figure 29:

ICV - PNP Gain vs. I_C

Poor current capability and low cutoff frequency

are well known limits of the standard lateral PNP.

Composite PNP-NPN power output stages have

been widely used, regardless their high saturation

drop. This drop can be overcome only at the ex-

pense of external components, namely, the boot-

strap capacitors. The availability of 4A isolated

collector PNP (ICV PNP) adds versatility to the

design. The performance of this component, in

terms of gain, V_CEsatand cut-off frequency, is

shown in fig. 29, 30, 31 respectively. It is realized

in a new bipolar technology, characterized by top-

bottom isolation techniques, allowing the imple-

mentation of low leakage diodes, too. It guaran-

tees BV_CEO> 20V and BV_CBO> 50V both for

NPN and PNP transistors. Basically, the connec-

tion shown in fig. 32 has been chosen. First of all

because its voltage swing is rail-to-rail, limited

only by the VCEsat of the output transistors,

which are in the range of 0.3Ω each. Then, the

gain VOUT/VIN is greater than unity, approxi-

mately 1+R2/R1. (VCC/2 is fixed by an auxiliary

amplifier common to both channel). It is possible,

controlling the amount of this local feedback, to

force the loop gain (A * β) to less than unity at fre-

quencies for which the phase shift is 180°. This

means that the output buffer is intrinsically stable

and not prone to oscillation.

Figure 30: ICV - PNP V_CE(sat) vs. I_C

Figure 32: The New Output Stage

Figure 31: ICV - PNP cut-off frequencyvs. I_C

In contrast, with the circuit of fig. 33, the solution

adopted to reduce the gain at high frequencies is

the use of an external RC network.

AMPLIFIER BLOCK DIAGRAM

The block diagram of each voltage amplifier is

shown in fig. 34. Regardless of production

spread, the current in each final stage is kept low,

with enough margin on the minimum, below which

cross-over distortion would appear.

below a given limit.

BUILT-IN PROTECTION SYSTEMS

The signal sets a flip-flop which forces the amplifier

outputsinto a high impedancestate.

Short Circuit Protection

The maximum current the device can deliver can

be calculated by considering the voltage that may

be present at the terminals of a car radio amplifier

and the minimum load impedance.

In case of DC short circuit when the short circuit

is removed the flip-flop is reset and restarts the

circuit (fig. 39). In case of AC short circuit or load

shorted in Bridge configuration, the device is con-

tinuously switched in ON/OFF conditions and the

current is limited.

Apart from consideration concerning the area of

the power transistors it is not difficult to achieve

peak currents of this magnitude (5 A peak).

However, it becomes more complicated if AC and

DC short circuit protection is also required.In par-

ticular, with a protection circuit which limits the

output current following the SOA curve of the out-

put transistors it is possible that in some condi-

tions (highly reactive loads, for example) the pro-

tection circuit may intervene during normal

operation. For this reason each amplifier has

been equipped with a protection circuit that inter-

venes when the output current exceeds 4A

Figure 35: Circuitry for Short Circuit Detection

Fig 35 shows the protection circuit for an NPN

power transistor (a symmetrical circuit applies to

PNP).The VBE of the power is monitored and

gives out a signal,availablethrough a cascode.

This cascode is used to avoid the intervention of

the short circuit protection when the saturation is

ing winter if two batteries are series connected to

crank the engine.

Load Dump Voltage Surge

The TDA 7360 has a circuit which enables it to

withstanda voltage pulse train on pin 9, of the type

shownin fig. 37.

Thermal Shut-down

The presence of a thermal limiting circuit offers

the following advantages:

1)an overload on the output (even if it is perma-

nent), or an excessive ambient temperature

can be easily withstood.

If the supply voltage peaks to more than 50V, then

an LC filter must be inserted between the supply

and pin 9, in order to assure that the pulses at pin9

will be held withinthe limits shown.

A suggestedLC networkis shownin fig. 36.

With this network, a train of pulseswith amplitude up

to 120Vand width of 2ms can be appliedat point A.

Thistypeof protectionis ON when thesupplyvoltage

(pulse or DC) exceeds18V. Forthis reason the maxi-

mumoperatingsupplyvoltageis18V.

2)the heatsink can have a smaller factorof safety

compared with that of a conventional circuit.

There is no device damage in the case of ex-

cessive junction temperature: all happens is

thatP_o(andthereforeP_tot) and I_darereduced.

Figure 36

Figure 37

The maximum allowable power dissipation de-

pends upon the size of the external heatsink (i.e.

its thermal resistance); Fig. 38 shows the dissi-

pable power as a function of ambient temperature

for different thermal resistance.

Figure 38: Maximum Allowable Power

Dissipation vs. Ambient Temperature

Polarity Inversion

Loudspeaker Protection

High current (up to 10A) can be handled by the de-

vice with no damage for a longer period than the

blow-out time of a quick 2A fuse (normally connected

in series with the supply). This features is added to

avoiddestruction,if during fittingto thecar, a mistake

on theconnectionofthe supplyismade.

The TDA7360 guarantees safe operations even

for the loudspeaker in case of accidental shortcir-

cuit.

Whenever a single OUT to GND, OUT to V_Sshort

circuit occurs both the outputs are switched OFF

so limiting dangerous DC current flowing through

the loudspeaker.

Open Ground

When the radio is in the ON condition and the

ground is accidentally opened, a standard audio

amplifier will be damaged. On the TDA7360 pro-

tection diodes are included to avoid any damage.

APPLICATION HINTS

Figure 40:

a) C_svr= 22 µF

This section explains briefly how to get the best

from the TDA7360 and presentssome application

circuits with suggestionsfor the value of the com-

ponents.These values can change depending on

the characteristics that the designer of the car ra-

dio wants to obtain,or other parts of the car radio

that are connected to the audio block.

To optimize the performance of the audio part it is

useful (or indispensable)to analyze also the parts

outside this block that can have an interconnec-

tion with the amplifier.

This method can provide componentsand system

cost saving.

Reducing Turn On-Off Pop

The TDA7360 has been designed in a way that

the turn on(off) transients are controlled through

the charge(discharge)of the Csvr capacitor.

b) C_svr= 47 µF

As a result of it, the turn on(off) transient spec-

trum contents is limited only to the subsonic

range.The following section gives some brief

notes to get the best from this design feature(it

will refer mainly to the stereo application which

appears to be in most cases the more critical from

the pop viewpoint.The bridge connection in

fact,due to the common mode waveform at the

outputs,does not give pop effect).

TURN-ON

Fig 40 shows the output waveform (before and

after the ”A” weighting filter) compared to the

value of Csvr.

Better pop-on performance is obtained with

higher Csvr values (the recommended range is

from 22uF to 220uF).

The turn-on delay (during which the amplifier is in

mute condition) is a function essentially of : C_{out ,}

perior, in particular the st-by pin can go low faster.

TURN-OFF

A turn-off pop can occur if the st-by pin goes low

with a short time constant (this can occur if other

car radio sections, preamplifiers,radio.. are sup-

plied through the same st-by switch).

GLOBAL APPROACH TO SOLVING POP

PROBLEM BY USING THE MUTING/TURN ON

DELAY FUNCTION

This pop is due to the fast switch-off of the inter-

nal current generatorof the amplifier.

In the real case turn-on and turn-off pop problems

are generated not only by the power amplifier,but

also (very often) by preamplifiers,tone controls,ra-

dios etc. and transmitted by the power amplifier to

the loudspeaker.

A simple approach to solving these problems is to

use the mute characteristicsof the TDA7360.

If the voltage present across the load becomes

rapidly zero (due to the fast switch off) a small

pop occurs, dependingalso on Cout,Rload.

The parameters that set the switch off time con-

stant of the st-by pin are:

♦ the st-by capacitor (Cst-by)

♦ the SVR capacitor (Csvr)

♦ resistors connected from st-by pin to ground

(Rext)

If the SVR pin is at a voltage below 1.5 V, the

mute attenuation (typ) is 30dB .The amplifier is in

play mode when Vsvr overcomes3.5 V.

With the circuit of fig 43 we can mute the amplifier

for a time Ton after switch-on and for a time Toff

after switch-off.During this period the circuitry that

precedes the power amplifier can produce spuri-

ous spikes that are not transmitted to the loud-

speaker. This can give back a very simple design

of this circuitry from the pop point of view.

The time constant is given by :

T ≈ Csvr • 2000Ω //Rext + Cst-by • 2500Ω //Rext

The suggestedtime constantsare :

T > 120ms with C_out=1000µF,R_L= 4ohm,stereo

T > 170ms with C_out=2200µF,R_L= 4ohm,stereo

If Rext is too low the Csvr can become too high

and a different approach may be useful (see next

section).

Figg 41, 42 show some types of electronic

switches (µP compatible) suitable for supplying

the st-by pin (it is important that Qsw is able to

saturate with V_CE≤ 150mV).

A timing diagram of this circuit is illustrated in fig

44. Other advantagesof this circuit are:

- A reduced time constant allowance of stand-by

pin turn off.Consequentlyit is possible to drive all

the car-radio with the signal that drives this pin.

-A better turn-off noise with signal on the output.

To drive two stereo amplifiers with this circuit it is

possible to use the circuit of fig 45.

Also for turn off pop the bridge configuration is su-

bridge configuration, a signal present on both the

input capacitors is amplified by the same amount

and it is present in phase at the outputs,so this

signal does not produce effects on the load.The

typical value of CMRR is 46 dB.

Figure 45

Looking at fig 46, we can see that a noise signal

from the ground of the power amplifier to the

ground of the hypothetical preamplifier is ampli-

fied of a factor equal to the gain of the amplifier

(2 * Gv).

Using a configuration of fig. 47 the same ground

noise is present at the output multiplied by the

factor 2 * Gv/200.

This means less distortion,less noise (e.g. motor

cassette noise ) and/or a simplification of the lay-

out of PC board.

The only limitation of this balanced input is the

maximum amplitude of common mode signals

(few tens of millivolt) to avoid a loss of output

power due to the common mode signal on the

output, but in a large number of cases this signal

is within this range.
