Description
The TDA2030A is a monolithic IC in a Pentawatt
package intended for use as a low-frequency
class-AB amplifier.
With VS max = 44 V it is particularly suited for more
reliable applications without regulated supply and
for 35 W driver circuits using low-cost
complementary pairs.
)-
The TDA2030A provides high output current and
has very low harmonic and crossover distortion.
The device incorporates a short-circuit protection
system comprising an arrangement for
automatically limiting the dissipated power so as
to keep the operating point of the output
transistors within their safe operating range. A
conventional thermal shutdown system is also
included.

TDA2030A
Multiway speaker systems and active boxes
Multiway loudspeaker systems provide the best possible acoustic performance since each
loudspeaker is specially designed and optimized to handle a limited range of frequencies.
Commonly, these loudspeaker systems divide the audio spectrum into two or three bands.
To maintain a flat frequency response over the hi-fi audio range, the bands covered by each
loudspeaker 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 segment of the audio spectrum. In this respect it is also
important to know the energy distribution of the music spectrum to determine the cutoff
frequencies of the crossover filters (see Figure 21). As an example, a 100 W three-way
system with crossover frequencies of 400 Hz and 3 kHz would require 50 W for the woofer,
35 W for the midrange unit and 15 W for the tweeter.

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 addition, active filters do not suffer from the typical defects of passive filters:
●
power less
●
increased impedance seen by the loudspeaker (lower damping)
●
difficulty of precise design due to variable loudspeaker 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 (6 dB/octave) can be recommended. The results 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 operate linearly well beyond the crossover frequency to avoid distortion.
A more effective solution, "Active Power Filter" by STMicroelectronics is shown in Figure 22.

The proposed circuit can realize combined power amplifiers and 12 dB/octave or
18 dB/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 required for the active filter operation.
The impedance at the pin (-) is of the order of 100 Ω, while that of the pin (+) is very high,
which is also what was wanted.

It employs 2nd order Butterworth filters with the crossover frequencies equal to 300 Hz and
3 kHz. The midrange section consists of two filters, a high-pass circuit followed by a lowpass network. With VS = 36 V the output power delivered to the woofer is 25 W at d = 0.06%

Another important field of application for active systems is music.
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 24)
consists of four amplifiers each driving a low-cost, 12-inch loudspeaker. This application can
supply 80 to 160 WRMS.

Transient intermodulation distortion (TIM)

TDA2030A
Transient intermodulation distortion (TIM)
Transient intermodulation distortion is an unfortunate phenomen associated with negativefeedback amplifiers. When a feedback amplifier receives an input signal which rises very
steeply, i.e. contains high-frequency components, the feedback can arrive too late so that
the amplifiers overloads and a burst of intermodulation distortion will be produced as in
Figure 25. Since transients occur frequently in music this obviously a problem for the
designer of audio amplifiers. Unfortunately, heavy negative feedback is frequency used to
reduce the total harmonic distortion of an amplifier, which tends to aggravate the transient
intermodulation (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 compared to the
input. This method suffers from serious disadvantages : the accuracy is limited, the
measurement is a rather delicate operation and an expensive spectrum analyser is
essential. A new approach applied by STMicroelectronics to monolithic amplifiers
measurement is fast, cheap (it requires nothing more sophisticated than an oscilloscope)
and sensitive - and it can be used for values as low as 0.002% in high-power amplifiers.

Transient intermodulation distortion (TIM)
The "inverting-sawtooth" method of measurement is based on the response of an amplifier
to a 20 kHz 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 Figure 26 cutting of the
shaded area and thus increasing the mean level. If this output signal is filtered to remove the
sawtooth, direct voltage remains which indicates the amount of TIM distortion, although it is
difficult to measure because it is indistinguishable from the DC offset of the amplifier. This
problem is neatly avoided in the IS-TIM method by periodically inverting the sawtooth
waveform at a low audio frequency as shown in Figure 27.

In the case of the sawtooth in Figure 27 the mean level was increased by the TIM distortion,
for a sawtooth in the other direction, the opposite is true. The result is an AC signal at the
output whose 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:

In Figure 28 the experimental results are shown for the 30 W amplifier using the TDA2030A
as a driver and a low-cost complementary pair. A simple RC filter on the input of the
amplifier to limit the maximum signal slope (SS) is an effective way to reduce TIM.

For example if an anti-TIM filter with a cutoff at 30 kHz is used and the max. peak-to-peak
output voltage is 20 V then, referring to the diagram, a slew rate of 6 V/ms is necessary for
0.1% TIM. As shown slew rates of above 10 V/ms do not contribute to a further reduction in
TIM.

Slew rates of 100 V/ms are not only useless but also a disadvantage in hi-fi audio amplifiers

Power supply
Power supply
Using a monolithic audio amplifier with non-regulated supply voltage, it is important to
design the power supply correctly. For any operation it must provide a supply voltage less
than the maximum value fixed by the IC breakdown voltage.
It is essential to take into account all the operating conditions, in particular mains
fluctuations and supply voltage variations with and without load. The TDA2030A
(VS max = 44 V) is particularly suitable for substitution of the standard IC power amplifiers
(with VS max = 36 V) for more reliable applications. An example, using a simple full-wave
rectifier followed by a capacitor filter, is shown in Table 6 and in the diagram of Figure 30.

A regulated supply is not usually used for the power output stages because 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 overdimensioning of the
circuit.
Doc ID 1459 Rev 2
17/23
Power supply
TDA2030A
Even if, with a regulated supply, higher output power can be obtained (VS is constant in all
operating conditions), the additional cost and power dissipation do not usually justify its use.
Using non-regulated supplies, there are fewer design restrictions. In fact, when signal peaks
are present, the capacitor filter acts as a flywheel, supplying the required energy. In average
conditions, the continuous power supplied is lower. The music power/continuous power ratio
is greater in this case than for the case of regulated supply, with space saving and cost
reduction.

Protections
7.1
Short-circuit protection
The TDA2030A has 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.
7.2
Thermal shutdown
)
s
(
ct
The presence of a thermal limiting circuit offers the following advantages:
1.
An overload on the output (even if it is permanent), or an above-limit ambient
temperature can be easily supported since Tj cannot be higher than 150 °C.
2.
The heatsink can have a smaller factor of safety compared with that of a conventional
circuit. There is no possibility of device damage due to high junction temperature. If, for
any reason, the junction temperature increases up to 150 °C, the thermal shutdown
simply reduces the power dissipation and the current consumption.
