rodDescription
te PThe TDA2030A is a monolithic IC in a Pentawatt
package intended for use as a low-frequency
leclass-AB amplifier.
soWith VS max = 44 V it is particularly suited for more
breliable applications without regulated supply and
Ofor 35 W driver circuits using low-cost
t(s) -complementary pairs.
Pentawatt (vertical)
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.

Multiway speaker systems and active boxes
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.
Figure 22. Active Power Filter
t(s)The proposed circuit can realize combined power amplifiers and 12 dB/octave or
uc18 dB/octave high-pass or low-pass filters.
dIn practice, at the input pins of the amplifier two equal and in-phase voltages are available,
roas required for the active filter operation.
PThe 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.
teThe component values calculated for fc = 900 Hz using a Bessek 3rd order Sallen and Key
lestructure are :

R2

R3

-Using this type of crossover filter, a complete 3-way 60 W active loudspeaker system is
t(s)shown in Figure 23.
cIt employs 2nd order Butterworth filters with the crossover frequencies equal to 300 Hz and
u3 kHz. The midrange section consists of two filters, a high-pass circuit followed by a low-
dpass network. With VS = 36 V the output power delivered to the woofer is 25 W at d = 0.06%
ro(30 W at d = 0.5%).
PThe power delivered to the midrange and the tweeter can be optimized in the design phase
tetaking in account the loudspeaker efficiency and impedance (RL = 4 Ω to 8 Ω).
leIt is quite common that midrange and tweeter speakers have an efficiency 3 dB higher than
Obso woofers.
