amp-TDA7052-circuit
The TDA7052 is a really easy to setup a build power amplifier performance.
The chip will be used by Philips Semiconductors, and a data sheet is created here. The circuits shown in this data sheet is very simple and requires only two other components (three if) it is a simple logarithmic volume control included.
The dotted line shows where the tracks must be cut. If this is done not done enough, the amplifier is not functioning. You can do this with a reasonable length of cutting tools at some retailers (recommended), but if you can not get one, it is possible to cut the title with a knife. You need a good knife that is small and select sharp. You also need to be very careful, it’s easy to slip and damage something, or yourself – that’s why I do not recommend doing this technique. Use a multimeter (or if you are not one, a battery and lamp / buzzer circuit) to ensure that there is no shortcut between the tracks to ensure that they have been cut completely and correctly. If you are below the line amplifier chip break (next down pins 4 to 5), then solder to the hole from you, or they go to jump with a cord. This route will remain uncut, or grounding pin 6 does not receive his or her needs.
If you are a beginner and have not done before, by all means in practice. Soldering on STRIPBOARD can be difficult and it is easy to use the title if too much is short. Once this is done, it is very difficult to sort without the proper equipment (ie, soldering equipment), you quickly become impatient and angry, most importantly, not too much solder used in the first place.
The 0.1UF (or 100nF) is a polyester capacitor with lead from a distance of 1 inch (10mm) as the one I received. The 220UF capacitor is an electrolytic capacitor rated at 16V. Positive is shown in the figure, is negative and the second terminal of the capacitor case is clearly indicated. Capacitor must be connected, right way up, otherwise you get a firework with higher voltage (ie, 9-12V). Injuries occur. Not more than 18V use on this amplifier, or it gets too hot and shut down. These units can run pretty hot and of course my chip was not happy running at high voltage (with sophisticated music could strain).
If you can lead an axial electrolytic capacitor produced, you can avoid an extra cable (and completely made tracks), which reflects the relationship through polyester capacitor. The positive next need to go to 1 on the TDA7052 pin.
If wiring of the speakers, not the floor. The TDA7052 uses BTL (Bridge Tied Load), which has up to 4 times the power of two amplifiers (which are embedded in the TDA7052). If you can not just expect that it speaks to the reason that it works.
As a final note, be sure to TDA7052 in the right way before you solder it. The diagram shows a semicircle on the chip. This should be a semicircle on the chip itself to, and it must also be at the top. When the semicircle can not see, you’re looking for a dash, or printed circle on the left side where it should be. This indicates Pin 1, which means that the chip should be left to put the circle on top. Put the chip in the wrong direction and it will not be forgiven, and you need to get better, believe me, I have (made a fool)!

Soldering is required to determine the components on the board.
