Is there any reason why the input capacitor C1 has such a huge voltage rating well above the theoretical maximum of Jeffery Lockmiller on November 7, at 5: Im beginning to not trust this beast. Datasheet article, thanks a lot. And I have a few questions: Bearing in mind most is subjective, though differences between components of different materials do have a definite measurable difference e.

The two silver mica capacitors 47pF and pF appear to be reversed in your pictures. Depending on the rectifier and diodes used, this should be anywhere from 1. A very nice explanation.

To convert voltage gain to decibels db gain, use this formula:. Thanks a lot for this awesome project. I calculated the total cost of accuiring these exact components in The Netherlands europe: Use low ESR bulk storage caps and minimize inductance lengths.

All the best John Reply.

Cant wait to see post on power supply! The formula to use is:.

Most of the time the controls pcb will be mounted parallel towards the front of the amplifier. I think this is an omission in the article. There are two schools of thought here.

Where would i put in a stereo potentiometer for volume control Reply. The combination of bulk caps should provide low impedance current throughout datwsheet frequency band for the load.

Whats up with that. Chip amps sound mediocre Reply. The sound is fantastic, however I can not reach it but the power is far from expected. 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.

Robert Reed on October datasneet, at 1: Brad on November 15, dahasheet 5: Please double check the information below, as I do not have alot of knowledge about electronics yet I am a newbie. The thermal resistance of the TF version plus thermal paste is about 2.

Dave on November 1, at George on October 19, at 8: Martin Arh on March 6, at 2: The heatsink is huge. The minimum gain setting of your amplifier will depend on your input voltage, speaker impedance, and output power according to the formula:.

Imho not adding controls is a good idea if you already have a control on your sound producing devices connected to this amplifier. I could send them to you for the amount of the postage.

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

Howeveris it possible to go directly to EDA with info you posted for the amplifier board? Low current grounds are the ground feeds to the input circuitry and feedback loop.

I looked all over lm3886tf it and cannot find it. PCB design also has a major influence on the performance of your amplifier. I would like to better understand how to set a value for lm38886tf cutoff at the feedback loop. In order to bring this down to a more reasonable level, I decided on using 4.

I will definetly try a build on my own. Get from a reputable supplier components specialists rather than ebay.
