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

If the currents at the non-inverting input pin 9 and the inverting input pin 10 are different, a voltage will develop between them. However, due to lack of deep knowledge in electronics, the project was lagging behind. Congratulations for the excellent post!

MBBS on October 15, at The best way to determine values for R f2 and C f is with circuit simulation software such as LTSpice. Hopefully my reply helps, if not… whatever.

The datasheet gives a value of 2. Liwei Sheng on June 7, at 4: I signed up for the partslist but I am not recieving any partslists, can someone upload lm3886tt partslist, thank you.

Some designs used only these parts For input: I have just a question: I live in Manila, Philippines. Second is to place fuse at the output end of the lytics. I am asking for information by email desoto wp. Robert Reed on August 15, at It just does not get better than that! Mohammad fahmawi on September 17, at 4: I do not care particular brands of capacitors or any other components as long as their specs meet requirements. Thus, I was wondering if you could state the specifications of eatasheet amp, distortion and noise characteristics so it can be compared to other LM designs, so see if one needs to improve anything.

Did you forget it? Cant wait to see post on power supply! Thank you for your excellent work on this guide. Since the inductor will be carrying the full output current of the amplifier, the wire should be heavy gauge.

I am interested in vatasheet two amplifier plates and one power supply. This setup drives them quite well. Fusing both AC line input and power rails are the best but more work and expense. Email me new tutorials and very occasional promotional stuff: Does anyone have a rough cost of building this amp??

Please double check the information below, as I do not have alot of knowledge about electronics yet I am a newbie. Robert Reed on August 15, at 3: You could even add a DIV at the top of the web page with a.

Victor H Faucheret on March 27, at I made an amp with LM in Buy a bigger case. George Riad on February 3, at 5: Chip amps sound mediocre Reply. Great project; thank you for sharing.

Awesome writeup, many thanks! The best article ever.

I started with 1. There are two schools of thought here. Success with the build, Ed. The PCB has 2 holes for the diodes, but the parts list specifies a 3 pin diode.
