There are many circuits on the net but again they do not explain any design aspects completely. The combination of bulk caps should provide low impedance datasheeg throughout the frequency band for the load.

What could be wrong?

Buy a bigger case. Although its a bit more work, I prefer the T version for the 0.

Which is close enough to 27 db, and above the I agree to let Circuit Basics store my personal information so they can email me the file I requested, and agree to the Privacy Policy Email me new tutorials and very occasional promotional stuff: The two Thiele networks are located close datashewt the speaker output terminals. Could you please add a print stylesheet to the website, where all the unnecessary stuff navigation, newsletter subsciption, social links, footer, etc is hidden and the content datxsheet has full width?


Thanks for your reply, Robin! Thank you for sharing this documented design guide for LM Does anyone have a rough cost of building this amp?? The lm3886td is fantastic, however I can not reach it but the power is far from expected. High current grounds are the ground feeds to the power supply decoupling capacitors, the Zobel network, and the speakers.

That can be found with this formula:. I would like to ask some questions. Thank you for this really great article. If I may offer my observations, which are purely subjective though based and no doubt influenced by research The power supply and each of the individual components do have a massive influence, especially as there are so few of them.

Alessandro Raco on December 23, at I made an amp with LM in The datasheet gives a value of 2.

Also, at the same time provide IC centric datashewt of the supply. At high frequencies, the impedance of C sn is very low, so high frequency current is shorted to ground.

Sascha on April 25, at 7: Thanks a million for the detailed top quality guidance. Use the diagram below as a guide for wiring the various parts together:. eatasheet

The highs are clear, but not harsh at all. Overture Application Note AN Dan, I dont remember but I dont think so. I am asking for information by email desoto wp. I like the way you treat ground connections. John- in regards to the case, the T version is non isolated meaning the back datasheet the case is clean metal connected directly to the -V supply which requires electrically insulating it from the heat sink.

Robert Reed on October 31, at 1: A pre-amp with tone controls would be also be a welcome. Satasheet my reply helps, if not… whatever.

Rb before Rin or Rin before Rb? The board layout has datashet for flexibility which will allow for experimenting with components. The TF version is isolated and mounts directly to the heat sink.
