I have just finished asembling the bridge version and I am impressed of the quality and the power of this IC!

LM Datasheet(PDF) – Unisonic Technologies

I use 50v for all polarized daatsheet and v for non-polarized ,20k potentiometer and powered by 3v rechargeable battery. Hey, how can I add the input to the speaker? The question is; are they interconnected on those points. You can also combine capacitors in parallel or series to get other values: 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 datxsheet sound but now the output is way too noisy.

But using the values you used should still give you sound, so there must be something else wrong. Yeah, it is pretty good, datashee What is the diagram software that you used to create these circuit diagrams? Simple Amplifier Circuit […]. I wanna make an amplifier use for 6 spkr.

Hey Kirk, You need to use an audio mini jack to plug into your laptop. But not more than lm4863x can handle. FYI, ive lost 4 radios in 3 months through crime and im done buying new radios. Hey, Check the datasheet of your potentiometer to find out the pin configuration, then match that with the diagram above. Im trying to use them all in my car as a complete built in system, without using a radio that can easily be stolen.


Dual 2.2W Audio Amplifier Plus Stereo Headphone Function

Hello im very new to all of this. The IC is probably running out of power. Well, I guess this article is a start. Hello Oyvind, Thanks for this website. This dot means that they should be connected. I have been looking for a good stereo amplifier circuit diagram for a long time.

Also, can you help me with the Potentiometer? It is very helpful. Boomer audio power amplifiers are designedplane, and finally, surrounding air. Is the circuit is dataxheet to withstand the power supply? Hi, Yes they are all connected.

And one more thingi think i should add, I am using USB power supply.

The Simplest Amplifier Circuit Diagram

Each channel needs 3 pins. How can I connect the two inputs to my laptop if I build this on a breadboard? Yes, 25V should be fine I think. But if you build a mono amplifier, you only need a standard pot with 3 pins.

Mini jack on one side, loose wires on the other side to plug into your breadboard. You can also make a 5W mono amplifier out of it. For splitting the signal, you can use resistors for basic splitting. For example from Jameco: If you love building things with electronics or would love tocheck out Ohmify. Maybe your old speakers just had too low Watt-rating… Anyway, great that you got it working! Boomer audio power amplifiers were designed specifically to provide high qualitySemiconductor Corporation DS www.


It is so simple to build that I put it together on a strip board in just a few hours.

It was always something that made me hesitate. 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. I enjoy seeing constructed circuits.

Hy guys my problem is i dont know where to buy those printed circuit boards i live at durban. Check out page 5 in the datasheet for circuit examples: Please mentioned voltage of capacitors to make the circuit useful for beginners….

A dual potmeter allows you to connect both left and right channel on one potentiometer. Hi Andy, If the sound is very low, you can try to increase the volume of your input device. Hi, For example from Jameco: I have wireless bluetooth speakers that came with my phone that i want to put front in-dash, a TEAD circuit from an old treadmill and a TEA that i got from an old hi-fi. The LM is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, willcustomer-specified closed-loop responses.
