DIY amplifier

The LA4440 microcircuit is a very attractive element for electronics because it has a simple switching circuit, low supply voltage and low cost of purchase. It can be used in stereo mode or bridged both channels

Every radio amateur must assemble an audio power amplifier at least once in his life. In this example, just such a sample with a power of 500 W is presented. This model is assembled quickly, literally in 1 hour. Amplifier class - AB, analogue

I needed to assemble a power amplifier. I have S30 speaker systems. Initially I planned to install a ready-made amplifier board into the case. After rummaging through the bins, I found the TDA2616 chip. I removed it from a non-working TV.

Despite the abundance of powerful microcircuit and transistor audio amplifiers, there is always a need to have a small portable stereo amplifier that does not require powerful power. Just such a thing can be built on the TDA1517P chip, its other

As you know, the first transistors that replaced radio tubes were germanium. Their invention played a big role in the development of electronics, making electronic devices more functional, economical and

This chip, TDA2003, has found wide application in literally all types of audio systems - it can be found in portable speakers, car radios, computer speakers, televisions and even small music centers. Such

As you know, audio power amplifiers are divided into different classes. Amplifiers operating in class “A” can provide decent music sound quality due to the high quiescent current, but they have extremely low efficiency and consume a lot

Transistor amplifiers, despite the advent of more modern microcircuit amplifiers, have not lost their relevance. Getting a microcircuit is sometimes not so easy, but transistors can be removed from almost any electronic device, namely

The Internet now offers a huge number of different sound amplifiers, for every taste and color, to suit any need.As you know, even the most reliable amplifiers tend to fail, for example, due to improper operating conditions,

Good afternoon Now we will assemble a low frequency amplifier. The TDA2004 microcircuit is taken as the basis. It has two outputs, but the power of each individually is 8 watts, which is not so much. Therefore, we will use bridging. Such inclusion

Another option for a simple, low-power, but very useful amplifier, which is based on the LM386 chip. Its maximum output power is 0.5 watts, which is quite enough to cover a small room. The advantages of the amplifier

Now there is a huge variety of audio amplifier circuits on microcircuits, for any needs, for any supply voltage, with different output powers. Microcircuit amplifiers are easy to create and do not require special configuration, unlike

Now on the Internet you can find a huge number of circuits of various amplifiers on microcircuits, mainly the TDA series. They have quite good characteristics, good efficiency and are not that expensive, which is why they use such

External speakers, USB speakers and speakerphones and headsets are conquering the market of electronic devices today. It can be difficult for an inexperienced consumer to understand all these new products.Sometimes it turns out that most of them turn out to be

Hello friends. Today I will tell you how to make a small power amplifier using the tda2822m chip. Here is the circuit that I found in the datasheet of the chip. We will make a stereo amplifier, that is, there will be two speakers - right and left channels.

There are quite a few varieties of budget amplifiers and this is one of them. The circuit is very simple and contains only one microcircuit, several resistors and capacitors. The characteristics of the amplifier are quite serious, with such insignificant

This is the simplest audio amplifier, capable of delivering 50 watts of power to each of the four channels. This adds up to 200 watts of sound power. And this, as it turned out, is not the limit. The microcircuit on which the amplifier is built can give 80

I'd say it's just a super simple amp that contains all four elements and puts out 40 watts of power into two channels! 4 parts and 40 W x 2 power output Karl! This is a godsend for car enthusiasts, since the amplifier is powered by 12 Volts, full

This amplifier can be used by radio amateurs as a power amplifier in radios, players, various toys with sound effects, as a headphone amplifier, etc. The range of applicability is very wide.

There were only diagrams on these microcircuits on the Internet, but I couldn’t find the assembled amplifier. Operating mode AB, Supply voltage 10…32 Volts, Stereo configuration, Operating temperature 0…70 degrees. Such chips can be found in modern TVs

I found an unnecessary circuit board from a TV. The TDA203A microcircuit caught my eye. I know that TDA brand microcircuits are low frequency amplifiers, there is a lot of information about them on the Internet. I decided to build my own simple amplifier according to the circuit...

Today I would like to tell you about an amplifier which, in my opinion, is an excellent solution in terms of price-power-quality ratio. And so, today we have the STK series microcircuit in the leading role. stk chips are hybrid chips that

The idea of ​​creating a six-channel speaker system has existed for a long time. Having set a goal, I studied the characteristics of the sound card in detail and found out that it supports as many as 7 sound channels. Since I have a good understanding of electrical circuits, I

Today we will assemble a simple mono audio amplifier using the TDA2003 chip. The TDA2003 chip can be removed from an old radio or bought on the radio market. Other details too. The amplifier is powered by 3-12 volts. The sound source can be a player
