Dqtasheet this circuit my best guess would be to add a low-pass filter on the input side. Turn on power triac – proposed circuit analysis 0.
Hello, Oyvind, Thanks for your reply. Yes they are all connected. Check out page 4 on the datasheet. For example from Jameco: This board was made to comply with the design rules of Seeed Studio May Also, can you help me with the Potentiometer? Equating complex number interms of the other 6. I have purchased W sterio amplifier with USB and mic-2 kit i want to understand bass treble and volume wiring in 6-pin pot.
Trackbacks […] TEA — 2. You can also make a 5W mono amplifier out of it. Dec 248: You can read about the potentiometer here: It was always something that made me hesitate.
Oyvind, I manage to make my amp work but the problem i am facing now is the output volume is too low ,can you please help me? Hi, The input does no go to the speaker. If the input signal is too high, you will get clipping on the output. Check out the TEA datasheet for more information on that On the input side, you should use a dual potentiometer. I mean to ask what is current consumption of this circuit?

When I was tinkering with the circuit, I found that removing the uF capacitor connected to non working speaker and shorting the wire, the speaker starts receiving sound but now the output is way too noisy. Is there any shop have a complete part list for this stereo amplifier?
I am not a HiFi geek, I just wanted to build a simple stereo amplifier that could drive some speakers for my desktop computer. Not sure what pin that is, but check the datasheet and you will find info on all pins: Thanks for your help. The IC is probably running out of power.

Hi, Well, I guess this article is a start. Leave a Reply Cancel reply Your email address will not be published.
Hey Kirk, You need to use an audio mini jack to plug into your laptop. This amplifier is great to use together with some speakers to get sound on your desktop computer.
For splitting the signal, you can use resistors for basic splitting. Im only using my phone as the music player. Please give me some advice.
How to test the IC having part no. You might be able to skip some of them, depending on your power source. Could you tell me where I can buy it since I wanna start building it in a week? But if you build a mono amplifier, you only need 458d standard pot with 3 pins.

I want to try making a portable audio amplify for devices like cellphones, mp3 player, etc. Hello, I am facing a strange problem with this circuit. Skip to content Skip to primary sidebar Skip to footer I have been looking for a good stereo amplifier circuit diagram for a long time.

Maybe your old speakers just had too low Watt-rating… Anyway, great that you got it working! Digital multimeter appears to have measured voltages lower than expected. This dot means that they should be connected.
Check out the TEA datasheet for more information on that. And higher Watt-rating of the speaker just means it can handle more power.

But not more than it can handle. Why u was use soo many cap in circuit….?? Hey, The design I created was double-sided. Hey, how 5458d I add the input to the speaker? On the input side, you should use a dual potentiometer. Check the datasheet of your potentiometer to find out the pin configuration, then match that with the diagram above.
