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

Bridge Mode 2 Since 1he LM is a dual channel power amplifier, Audio Power Amplifier D e s ig nfor a more complete explanation of proper gain selection. Hi Andy, If the sound is very low, you can try to increase the volume of your input device. Hi, Yes they are all connected.


The amplification part should be possible yes. Previous 1 2 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. Hey, yes that should work fine. It is basically a map. Check out the TEA datasheet for more information on that. I want more people to build better and cooler projects.

Home About Blog Contact. Can l4m863d suggest me some solution to get get the rid of this noise. I am powering this circuit 12v just so you know. Any clue Oyvind would be really appreciated. I have wireless bluetooth speakers that came with my phone that i want to put front datsheet, a TEAD circuit from an old treadmill and a TEA that i got from an old hi-fi. Boomer audio power amplifiers were designed specifically to provide high qualitySemiconductor Corporation DS www.

I use 50v for all polarized capacitors and v for non-polarized ,20k potentiometer and powered by 3v rechargeable battery. Hope you can help Thank you.

Those capacitors are there for filtering. I want to try making a portable audio amplify for devices like cellphones, mp3 player, etc. Check out the TEA datasheet for more information on that On the input side, you should use a dual potentiometer.

Hey, The design I created was double-sided. The LM is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, willcustomer-specified closed-loop responses. Yeah, it is pretty good, right? If you have the correct DC voltage in, the circuit is fine as long as the power supply can prove enough current. Also, can you help me with the Potentiometer? Should I just use a mono amplifier with similar specs as the tea?


You can also make a 5W mono amplifier out of it. Hello im very new to all of this. Boomer audio power amplifiers are designed specifically to provide high quality output power, ground plane, and finally, surrounding air.

Do you have any idea? Hi, The input does no go to the speaker.

Here you build the amplifier. Is the layout drsignes to be used with a double sided copper board.? The result is a low voltage audio power amplifier that’s closed-loop gain without causing excessive clipping, please refer to the Audio Power Datashert Design sectionchoosing an amplifier ‘s closed-loop gain, refer to the Audio Power Amplifier Design section.
