Despite the abundance of powerful microcircuit and transistor sound amplifiers, there is always a need to have a small portable stereo amplifier that does not require powerful power. Just this one can be built on the TDA1517P chip, its another
As you know, audio power amplifiers are divided into different classes. Amplifiers working in class “A” can provide decent sound quality of music due to the high quiescent current, but they have extremely low efficiency, they consume a lot of current
Hello friends. Today I will tell you how to make a small power amplifier on a tda2822m chip. Here is the circuit I found in the datasheet of the chip. We will make a stereo amplifier, that is, there will be two speakers - the right and left channels.
This simplest audio frequency amplifier is capable of delivering 50 watts of power to each of the four channels. In total, it turns out 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 would say that this is just a super simple amplifier containing all four elements and delivering 40 watts into two channels! 4 parts and 40 watts x 2 power output Carl! This is a godsend for motorists, as the amplifier is powered by 12 Volts, full
The Internet had only circuits on these microcircuits, but the assembled amplifier was never found. Operating mode AB, Supply voltage 10 ... 32 Volts, Stereo configuration, Operating temperature 0 ... 70 degrees. Such microcircuits can be found in modern TVs
I found an unnecessary board from the TV. My eye was attracted by the TDA203A chip. I know that TDA microcircuits are low-frequency amplifiers, there is a lot of information about them on the Internet. I decided to assemble my own simple amplifier according to the scheme ...
The idea of creating a six-channel speaker system has existed for a long time. Having set a goal, I studied in detail the characteristics of the sound card and found out that it supports as many as 7 channels of sound. Since I am well versed in electrical circuits, I decided
Today we will build a simple mono audio amplifier on the TDA2003 chip. The TDA2003 chip can be dropped out of the old radio or bought on the radio market. The rest of the details as well. The amplifier is powered by 3-12 volts. The sound source may be a player
Perhaps the most difficult part of the design of amplifiers for supplying a subwoofer channel from the on-board network is 12 volts. There are a lot of reviews about it in different forums, but it’s very difficult to make a really good converter on the advice of experts, make sure
Surely many would like to have a 5.1 audio system at home but for the frequent prices of such amplifiers are quite large. I’ll tell you how simple and not very expensive to assemble a 4-channel amplifier for such a system. Rummaging on the Internet, I chose the most
