A Complete Guide to Design and Build a Hi-Fi LM3886 Amplifier

Consent to store personal datashert Dr Dorkmeister on May 21, at Or is it just because the part is lm386tf manufactured like that by Mundorf? What could be wrong? The actual diode has only 2 posts rather than 3 as is shown in the data sheet. Sound quality is severely compromised when the SPiKe circuitry is enabled, so to prevent this we need a heat sink with a thermal resistance low enough to dissipate the maximum power dissipated by the LM Howeveris it possible to go directly to EDA with info you posted for the amplifier board?

Robert Reed on August 15, at 3: Setting it too low might make your amplifier too quiet. If datasheet were a way to trade email addresses, I think that I have a few of the amplifier boards in my shack.

Though I have no expertise in Physics, was able to understand the technical things in this article. Thanks a lot for sharing this wonderful job.


I would also like to lm3886gf a follow up post with details on the power supply. It is hard to resist from building this amp: I would like to know if there is a way to buy the power supply PCB instead of making it from scratch.

I do not care particular brands of capacitors or any other components as long as their specs meet requirements. Robin P Clarke on May 29, at I have built a couple of the Peter Daniels Audiosector Gainclones before. Use two smaller transformers and put bridge and caps on amplifier board.

You use the TF version, why is that? Would be awesome to have links to getting the chosen audio components too.

I also really like how you supplied the calculations for determining the size of the components. The thermal resistance of the gap between the chip case and the heat sink.

I would not call this basics. Second is there any need for preamp as my audio source would be a laptop or a smatphone. The 1nf capacitor at each input terminal are connected from the positive side to ground or or from the ground to chassis?

You can add an input selector knob if you want more inputs on the same controls-pcb and then mount the pcb parallel to where your control knobs datashet be. However the big lytics will continue to conduct until fully discharged and continue to do damage for faulty down stream components.


In there you could put things like a publishing date and a copyright notice, keywords, a table of contents, social link URLs written in full as normal text instead of just blue words in the article, etc. This is datasehet Excel spreadsheet that calculates output power, heat sink size, gain, and other useful parameters:. Could you also consider doing a solid state discrete power amp with dual dc power supply.

Great job, very well explained. Robert on July 21, at 9: But the question is if the motors operation would generate enough electric fields to lmm3886tf generating noise in the amplifier?

Circuit Basics on June 19, at 6: You can really feel it. Datashewt these resistors vary much between the two channels, the gains will be different and one channel will be louder than the other. The is in fact the smaller- the 47pF is the bigger one!

Which is close enough to 27 db, lm386tf above the Success with the build, Ed. Your email address will not be published. Francois on October 11, at 9: So the question is, if and how much would adding fans to near the circuit affect sound quality?
