But if you build a mono amplifier, you only need a standard pot with 3 pins. This is a really cool thing!

Hello Oyvind, Thanks for this website. I am not a HiFi […]. And one more thingi think i should add, I am using USB power supply. I wanna make an amplifier use for 6 spkr. The result is a low voltage audio power amplifier that produces 2. Hy guys my problem is i dont know where to buy those datashwet circuit boards i live at durban.

Check out page 4 on the datasheet. But if you want more power, check the datasheet for how to connect the outputs in mono-setting. Check out the TEA daatasheet for more information on that. On the input side, you should use a dual potentiometer. Buy lm463d tablet power supply 5V 2A, for fast charging and check current consumption with a multimeter. If you have the correct DC voltage in, the circuit is fine as long as the power supply can prove enough current.

Please what should I do. Check out page 5 in the datasheet for circuit examples: You can also make a 5W mono amplifier out of it. So first, check if you have the noise problem when the volume is turned down: Thanks for your quick reply, I tried your suggested solution and yes the noise is still present at lower volumes.

I am thinking of putting one in my kitchen and in my bathroom also. Boomer audio power amplitiers were designed specifically to provideconditions.

LM Boomer Audio Power Amplifier Series datasheet & applicatoin notes – Datasheet Archive

Each channel needs 3 pins. I need to boost a signal sixfold before I divide it by 6 to send to 6 different destinations. Driving 1W into an 8 Load Power Output: Hey, Check the datasheet of your potentiometer to find out the pin configuration, then match that with the diagram above. Please mentioned voltage of capacitors to make the circuit useful for beginners…. Try switching the inputs and see if this gives you lk4863d output on the other channel.

Hope you can help Thank you. Should I just use a mono amplifier with similar datashewt as the tea? But using the values you used should still give you sound, so there must be something else wrong. For splitting the signal, you can use resistors for basic splitting. But recently I found this awesome little chip called TEA! Nice and useful post.

With this circuit my best guess would be to add a low-pass filter on the input side. Boomer audio power amplifiers were designed specifically to provide high qualitySemiconductor Corporation DS www. The question is; are they interconnected on those points.

The LM is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, willcustomer-specified closed-loop responses. The LM has two operational. 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.

Here you build the amplifier. Check out the TEA datasheet for more information on that On the input side, you should use a dual potentiometer.

The Simplest Amplifier Circuit Diagram

Why Do We Use Capacitors in this circuit. Hey Kirk, You need to use an audio mini jack to plug into your laptop.

Are the potentiometers needs to be a Dual Potentiometer 6 pins or can I use 3 pin potentiometer? Those capacitors are there for filtering. Another advantage of the differential bridge output is no net DC voltageamplifier is higher internal power dissipation for the same conditions.
