This stereo amplifier circuit diagram is cheap and simple. 2.5W * 2 Stereo Amplifier. The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. The Simplest Audio Amplifier Circuit Diagram. I have been looking for a good stereo amplifier circuit diagram for a long time. I am not a Hi. Fi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. All the schematic diagrams that I could find seemed to involve lots of hard- to- find components or you had to use it together with a pre- amplifier or some other amplifier stage. It was always something that made me hesitate. But recently I found this awesome little chip called TEA2. You only need a few capacitors to make a decent stereo amplifier out of it. It is so simple to build that I put it together on a strip board in just a few hours. W * 2 Stereo Amplifier. The amplifier circuit diagram shows a 2. W * 2 stereo amplifier. You can also make a 5. W mono amplifier out of it. A dual potmeter allows you to connect both left and right channel on one potentiometer. This amplifier is great to use together with some speakers to get sound on your desktop computer. I am thinking of putting one in my kitchen and in my bathroom also. Then maybe hook them up to my home network and stream music from a server =) There are many possibilities when you can make such a cheap amplifier. Make any surface into a speaker with this DIY Speaker Kit from Makershed. Amplifier circuit diagram and parts list. Parts list. Part. Value. Description. C1. 10. 0. The most expensive component is the potentiometer (about $3- 4). Download Eagle schematics and board layout. Here is the schematics (Eagle), PCB board layout (Eagle) and Gerber files. This board was made to comply with the design rules of Seeed Studio (May 2. Stereo- Amplifier- TEA2. Eagle)How Can I Help You? I want more people to build better and cooler projects. Everyone can improve even if they are complete beginners or have built many circuits from before. Click here to see how I can help you. Return from Amplifier Circuit Diagram to Circuit Ideas. Share on social media. Datasheet. Quotefx - RFQ ? W Car Subwoofer Amplifier. It consist of three blocks. Push- pull converter. This is a copy of very good and tested AVT2. Schematic and polish description – LINK. This converter is based on the TL4. KA7. 50. 0) driver. Over- voltage protection take care of the power amplifier safety – driver will shut- down if voltage exceeds 1. V on input (converter has no voltage stabilization). Under- voltage protection take care of the car battery discharge – driver will shut- down if voltage drops to 9. V and below. Current protection take care of switching transistors and general security of whole circuit. This is a very nice, simple, and reliable solution – if switching transistors are more loaded, then we get higher voltage on IN+ of build in comparator. This is measured by simple circuit consist of 1. N4. 14. 8 diodes and RC (1. K,1. 0n) filter. On IN- , we can adjust compare voltage with PR1 potentiometer and if voltage on IN+ exceeds that adjusted one, driver will shut- down. Green diode means normal work, red diode means that one of protections has disabled the driver. To restart, switch off and then on supply or REMOTE voltage. Soft- start circuit allows to slowly start converter and charge a big capacitance at the output. You can make your own or take one from ATX (or AT) pc power supply. Use the 5. V and 1. V lines, it has a very nice transmission – 2,4x. That means, if we put +1. V line, we get 2,4x more voltage on 1. V line – about +/- 3. V to power audio amplifier. This is very good solution, but not every one transformer is good to use. First of all we must to separate common grounds for output lines (1. V and 5. V lines) – it is very important, otherwise our +1. V battery voltage will be connected to power amplifier ground – this eliminate using this circuit in a car – because amplifier ground is a signal ground. Switching frequency is 5. KHz, this is good for ATX/AT transformers. Lower frequency will cause transformer core to heats up. If you use your own transformer, you can lower switching frequency to reduce losses in switching. Do that by mounting bigger capacitor on pin. F will give frequency about 5. KHz, 1,5n. F give 3. KHz. Switching transistors do not requires any kind of cooling if converter works properly. You can replace the IRFZ4. N for other transistors, we need only 1. W of output power and IRFZ4. N can provide up to 3. W. Converter driver is powered from REMOTE line, and it drains not more than 5. A from that line. This is a simple circuit with one operational amplifier, see schematic for more. Supplied with symmetric voltage +1. V/- 1. 2V provided from 1. V zener diodes voltage limiter. TDA7. 29. 4 chip in its typical application, see datasheet for more. MUTE and ST- BY circuit modified – see fig. V. Two capacitors at the power amplifier chip are also push- pull converter output capacitors. Make two air- jumpers on pcb, from rectifying diodes to amplifier capacitors – use thick wires. Input capacitor C4 must have at least 4. F, on its capacity and efficiency depends the output power. NECESSARILY use a 1. A fuse on battery line. This is not for the beginners, launching of push- pull converter requires some knowledge and equipment (i. However you can build this using exactly same values components like on the schematic and simply use it. When doing a first launch, use power- supply with current limiting.
