TDA2030A  
18W Hi-Fi AMPLIFIER AND 35W DRIVER  
DESCRIPTION  
The TDA2030A is a monolithic IC in Pentawatt  
package intended for use as low frequency class  
AB amplifier.  
With VS max = 44V it is particularly suited for more  
reliable applications without regulated supply and  
for 35W driver circuits using low-cost complemen-  
tary pairs.  
The TDA2030A provides high output current and  
has very low harmonic and cross-over distortion.  
PENTAWATT  
Further the device incorporates a short circuit pro-  
tection system comprising an arrangement for  
automaticallylimiting the dissipated power so as to  
keep the working point of the output transistors  
within their safe operating area. A conventional  
thermal shut-down system is also included.

MULTIWAY SPEAKER SYSTEMS AND ACTIVE  
BOXES  
Multiway loudspeaker systems provide the best  
possible acoustic performance since each loud-  
speaker is specially designed and optimized to  
handle a limited range of frequencies. Commonly,  
these loudspeaker systems divide the audio spec-  
trum into two or three bands.  
To maintain aflat frequencyresponseover theHi-Fi  
audio range the bands covered by each loud-  
speaker must overlap slightly. Imbalance between  
the loudspeakers produces unacceptable results  
therefore it is important to ensure that each unit  
generates the correct amount of acoustic energy  
for its segmento of the audio spectrum. In this  
respect it is also important to know the energy  
distribution of the music spectrumto determine the  
cutoff frequenciesof the crossover filters (see Fig-  
ure 18). As an example a 100W three-way system  
with crossover frequencies of 400Hz and 3kHz  
would require 50W for the woofer, 35W for the  
midrange unit and 15W for the tweeter.

TDA2030A  
Figure 18 : Power Distribution versus Frequency  
A more effective solution, named ”Active Power  
Filter” by SGS-THOMSON is shown in Figure 19.  
Figure 19 : Active Power Filter  
The proposed circuit can realize combined power  
amplifiers and 12dB/octave or 18dB/octave high-  
pass or low-pass filters.  
In practice, at the input pins of the amplifier two  
equal and in-phase voltages are available, as re-  
quired for the active filter operation.  
Both active and passive filters can be used for  
crossovers but today active filters cost significantly  
less than a good passive filter using air cored  
inductors and non-electrolytic capacitors. In addi-  
tion, active filters do not suffer from the typical  
defects of passive filters:  
The impedanceat the pin(-) is of theorder of 100,  
while that of the pin (+) is very high, which is also  
what was wanted.  
The component values calculated for fc = 900Hz  
using a Bessek 3rd order Sallen and Key structure  
are :  
- power less  
C1 = C2 = C3  
R1  
R2  
R3  
- increased impedance seen by the loudspeaker  
(lower damping)  
22nF  
8.2kΩ  
5.6kΩ  
33kΩ  
- difficulty of precise design due to variable loud-  
speaker impedance.  
Obviously, active crossovers can only be used if a  
power amplifier is provided for each drive unit. This  
makes it particularly interesting and economically  
sound to use monolithic power amplifiers.  
In some applications, complex filters are not really  
necessary and simple RC low-pass and high-pass  
networks (6dB/octave)can be recommended.  
Using this typeof crossoverfilter, a complete 3-way  
60W active loudspeaker system is shown in Fig-  
ure 20.  
It employs 2nd order Buttherworth filters with the  
crossover frequenciesequal to 300Hz and 3kHz.  
The midrange section consists of two filters, a high  
pass circuit followed by a low pass network. With  
VS = 36V the output power delivered to the woofer  
is 25W at d = 0.06% (30W at d = 0.5%).  
The result obtained are excellent because this is  
the best type of audio filter and the only one free  
from phase and transient distortion.  
The rather poor out of band attenuation of single  
RC filters means that the loudspeaker must oper-  
ate linearly well beyondthe crossover frequency to  
avoid distortion.  
The power delivered to the midrange and the  
tweeter can be optimized in the design phase  
taking in account the loudspeaker efficiency and  
impedance (RL = 4to 8).  
It is quite common that midrange and tweeter  
speakers have an efficiency 3dB higher than-  
woofers.

MUSICAL INSTRUMENTS AMPLIFIERS  
can be used down to the values as low as 0.002%  
in high power amplifiers.  
Another important field of application for active  
systems is music.  
Figure 22 : Overshoot Phenomenon in Feedback  
In this area the use of several medium power  
amplifiers is more convenient than a single high  
power amplifier, and it is also more realiable.  
A typical example (see Figure 21) consist of four  
amplifiers each driving a low-cost, 12 inch loud-  
speaker. This application can supply 80 to  
Amplifiers

Figure 21 : High Power Active Box  
for Musical Instrument  
The ”inverting-sawtooh” method of measurement  
is basedon the response of an amplifier to a 20kHz  
sawtooth waveform. The amplifier has no difficulty  
following the slow ramp but it cannot follow the fast  
edge. The output will follow the upper line in Fig-  
ure 23cutting of the shaded area and thusincreas-  
ing the mean level. If this outputsignal is filtered to  
remove thesawtooth, direct voltage remains which  
indicates the amount of TIM distortion, although it  
is difficult to measure because it is indistinguish-  
able from the DC offset of the amplifier. This prob-  
lem is neatly avoided in the IS-TIM method by  
periodically inverting the sawtooth waveform at a  
low audio frequency as shown in Figure 24.  
TRANSIENT INTERMODULATION DISTOR-  
TION (TIM)  
Transient intermodulation distortion is an unfortu-  
nate phenomen associated with negative-feed-  
back amplifiers. When a feedback amplifier  
receives an input signal which rises very steeply,  
i.e. containshigh-frequencycomponents,the feed-  
back can arrive too late so that the amplifiers  
overloads and a burst of intermodulationdistortion  
will be produced as in Figure 22. Since transients  
occur frequently in music this obviously a problem  
for the designer of audio amplifiers. Unfortunately,  
heavy negative feedback is frequency used to re-  
duce the total harmonic distortion of an amplifier,  
which tends to aggravate the transient intermodu-  
lation (TIM situation. The best known method for  
the measurement of TIM consists of feeding sine  
waves superimposed onto square waves, into the  
amplifier under test. The output spectrum is then  
examined using a spectrum analyser and com-  
paredto theinput.This methodsuffersfromserious  
disadvantages: the accuracy is limited, the meas-  
urement is a rather delicate operation and an ex-  
pensive spectrum analyser is essential. A new  
approach (see Technical Note 143) applied by  
SGS-THOMSONto monolithicamplifiers measure-  
ment is fast cheap-itrequires nothingmore sophis-  
ticated than an oscilloscope - and sensitive - and it

11/15  
TDA2030A  
In the case of the sawtooth in Figure 25 the mean  
level was increased by the TIM distortion, for a  
sawtooth in the other direction the opposite is true.  
Figure 26 : TIM Design Diagram (fC = 30kHz)  
The result is an AC signal at the output whole  
peak-to-peak value is the TIM voltage, which can  
be measured easily with an oscilloscope. If the  
peak-to-peak value of the signal and the peak-to-  
peak of the inverting sawtooth are measured, the  
TIM can be found very simply from:  
VOUT  
Vsawtooth  
TIM =  
100  
In Figure25 the experimentalresults are shown for  
the 30W amplifier using the TDA2030Aas a driver  
and a low-cost complementary pair. A simple RC  
filter on the input of the amplifier to limit the maxi-  
mumsignalslope (SS)is an effectivewayto reduce  
TIM.  
POWER SUPPLY  
Usingmonolithicaudioamplifierwith non-regulated  
supply voltage it is important to design the power  
supply correctly. In any working case it must pro-  
vide a supply voltage less than the maximum value  
fixed by the IC break-down voltage.  
Figure 25 : TIM Distortion versus Output Power  
It is essential to take into account all the working  
conditions,inparticularmainsfluctuationsand sup-  
ply voltage variations with and without load. The  
TDA2030A(VS max =44V) isparticularly suitablefor  
substitution of the standard IC power amplifiers  
(with VS max = 36V) for more reliable applications.  
An example, using a simple full-wave rectifier fol-  
lowed by a capacitor filter, is shown in the table 1  
and in the diagram of Figure 27.  
Figure 27 : DC Characteristics of  
50W Non-regulated Supply  
The diagram of Figure 26 originated by SGS-  
THOMSON can beused to find the Slew-Rate (SR)  
required for a given output power or voltage and a  
TIM design target.  
For example if an anti-TIM filter with a cutoff at  
30kHz is used and the max. peak-to-peak output  
voltage is 20V then, referring to the diagram, a  
Slew-Rate of 6V/µs is necessary for 0.1% TIM.  
As shown Slew-Rates of above 10V/µs do not  
contribute to a further reduction in TIM.  
Slew-Rates of 100/µs are not only useless but also  
a disadvantage in Hi-Fi audio amplifiers because  
they tend to turn the amplifier into a radio receiver.

SHORT CIRCUIT PROTECTION  
The TDA2030Ahas an original circuit which limits  
the current of the output transistors. This function  
can be considered as being peak power limiting  
rather than simple current limiting. It reduces the  
possibility that the device gets damaged during an  
accidental short circuit from AC output to ground.

Aregulatedsupplyis not usuallyused for thepower  
output stagesbecause of its dimensioning must be  
done taking into account the power to supply in the  
signal peaks. They are only a small percentage of  
the total music signal, with consequently large  
overdimensioningof the circuit.  
Even if with a regulatedsupply higheroutput power  
can be obtained (VS is constant in all working condi-  
tions), the additional cost and power dissipation do  
not usually justify its use. Using non-regulated sup-  
plies, there are fewer designe restriction. In fact,  
when signal peaks are present, the capacitor filter  
acts as a flywheel supplying the required energy.  
THERMAL SHUT-DOWN  
The presenceof a thermal limiting circuit offers the  
following advantages:  
1. An overload on the output (even if it is  
permanent), or an above limit ambient  
temperaturecan be easily supported since the  
Tj cannot be higher than 150oC.  
2. The heatsink can have a smaller factor of  
safety compared with that of a conventional  
circuit. There is nopossibility of devicedamage  
due to high junction temperature. If for any  
reason, the junction temperatureincreases up  
to 150oC, the thermal shut-down simply  
reduces the power dissipation and the current  
consumption.  
In average conditions, the continuous power sup-  
plied is lower. The music power/continuouspower  
ratio is greater in this case than for the case of  
regulated supplied, with space saving and cost  
reduction.
