Devrede TDA2050 Kullanılmış fakat :) isterseniz aynı pcbde LM1875 yada TDA2030 kullanabilirsiniz bu entegrelerin bacak bağlantıları aynı

Anfinin pcbsi Sprint layout ile hazırlanmış izleme ve çıktı almak için üçretsiz Sprint Layout Viewer programını kullanabilirsiniz besleme devresi için ek bir pcb hazırlamanıza gerek yok hepsi tek pcb üzerinde datasheet bilgilerine göre 32 wat güç verebiliyor

TDA 2050
is a monolithic integrated circuit in
Pentawatt package, intended for use as an audio
class AB audio amplifier. Thanks to its high power
capability the TDA2050 is able to provide up to
35W true rms power into 4 ohm load @ THD =
10%, VS = ±18V, f = 1KHz and up to 32W into
8ohm load @THD = 10%, VS = ±22V, f = 1KHz.
Moreover, the TDA 2050 delivers typically 50W
music power into 4 ohm load over 1 sec at VS=
22.5V, f = 1KHz.

LM1875
is a monolithic power amplifier offering very
low distortion and high quality performance for consumer
audio applications.
The LM1875 delivers 20 watts into a 4X or 8X load on
g25V supplies. Using an 8X load and g30V supplies, over
30 watts of power may be delivered. The amplifier is designed
to operate with a minimum of external components.
Device overload protection consists of both internal current
limit and thermal shutdown.
The LM1875 design takes advantage of advanced circuit
techniques and processing to achieve extremely low distortion
levels even at high output power levels. Other outstanding
features include high gain, fast slew rate and a wide
power bandwidth, large output voltage swing, high current
capability, and a very wide supply range. The amplifier is
internally compensated and stable for gains of 10 or greater.

TDA2030
is a monolithic integrated circuit in
Pentawatt® package, intended for use as a low
frequency class AB amplifier. Typically it provides
14W output power (d = 0.5%) at 14V/4W; at ± 14V
or 28V, the guaranteed output power is 12W on a
4W load and 8W on a 8W (DIN45500).
The TDA2030 provides high output current and has
very low harmonic and cross-over distortion.
Further the device incorporates an original (and
patented) short circuit protection system comprising
an arrangement for automatically limiting 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.
