Now I did the final check befor starting solder the bridged amplifier. Notify me of follow-up comments by email. Thanks, Sy Do Reply. The mid frequencies are very detailed, and the highs are not harsh at all.
Circuit Basics on April 13, at 5: Electronic circuits is a total new hoby for me and I found this site and it is a good start. For the larger value capacitors, electrolytics are the only option. Your email address will not be published. Figure 3 in the datasheet shows the output power vs. The quality is great.
The metal tab on the back of the TDA is connected to the ground pin pin 3. Another way to get a better bass response is to increase the size of the larger power supply decoupling capacitors, C7 and C Mabey you can say something about this point before I solder.
For me I am not an electrician it is very confusing. In a bridged configuration, two amplifier chips power a single speaker.
Resistors R2 and R5 set the gain of the amplifier. Actually there are two different datasheets. You can use any type of box depending on what you can find, but metal enclosures are preferred since they offer shielding from interference caused by fluorescent lights, radios, and cell phones.
This is to reduce the length of the traces connecting the capacitors to the chip. Hi, could I use amplifkcador amp suitable for headphones? The left channel gain is set by resistors R1 ampliricador R2, while the right channel gain is set by R6 and R7. Like the stereo amplifier, the bridged amplifier has a low pass RC filter at the output. Higher voltages will give you more output power. Capacitors can be very expensive if you go for the high-end audiophile brands.
The cutoff frequency is calculated the same way:.
The cutoff frequency is:. The information below should help you get the best sound without breaking the bank. I added 2 variable resistors 10k before the capacitors C1 and C2 to adjust volume for the left channel and the right channel. If I right, How to use only one variable resistor for adjusting the volume on 2 channels? Without a heat sink the chip will get extremely hot very quickly and become permanently damaged.
There is part missing namely: Metal film resistors are the best choice for audio. I do not mean it critacal but I see some differences in the pictures from the amplifier relative to the PCB before soldering. If you have any questions, be sure to let us know in the comments….
The low pass filter is formed by C6 and R4 in the left channel and C11 and R5 in the right channel. Divakar Pathak on June 24, at 6: The bass lacks a little punch, but the overall sound is very well balanced.
Hi, Electronic circuits is a total new hoby for me and I found this site and it is a good start. I wanted to ask, what is the resole that you used, high voltage capacitors in a circuit that will work on a amplifiacdor of 12 Volts.
The components you use in your amplifier will have a major effect on the sound quality. I have a question about the bridged Amp: Divakar Pathak on June 24, at 7: So all frequencies above Juan on October 3, at 7: Email me new tutorials and very occasional promotional stuff: Hello, I see your project very interesting. The ground planes help to reduce noise because they shield the circuit from radio frequencies.
