The datasheet has graphs that will tell you.

I am interested in recycling my old notebook speakers 2watts each to make a usb driven amplifier with 2.

An easy way to connect the audio input in these circuits is by cutting the 3.

I just want to ask if you can send me a copy of the schematics because im not used to bread boards which is I am really ashamed of, LOL. I have a suggestion….

Jefferson Yagdulas on March 3, at 3: Could u please send me an updated schematic? Louis on November 28, at 1: Venkatagireesh on October 27, at Marius on April 3, at Mike on September 13, at 7: Like is there any power rating associated?


Anand on February 9, at 4: Suman Dutta on August 12, at 6: Lineman on October 25, at 4: Please dtaasheet me the schematic diagram. Simon Tay on August 28, at 8: Dear Alex the same circuit u can use by connecting pin 1 and 8 with jumper works well with 3. Ola on June 24, at Notify me of new posts by email.

I need to break-in my new subs. I used a 4 ohm speaker Reply. Sir you can use a 3. How can I do it??

Murat on March 8, at 2: Rafael on April 13, at 2: Thank you very much for sharing. If I were you I would rebuild the entire circuit with all the components replaced including the chip and the speaker. Simon Tay on September 12, at 5: Sir I have 4 ohm 2speakers so what amplifier I should use Reply. Sunil Vishwakarma on October 10, at 9: This means the positive pole of this cap is connected to the source of your signal, for example, a guitar. It keeps distorting the signal and squealing, or cutting it out all together.


Do i need to learn C programme. Thanks btw for this great article and all the others! Here are links to those articles: Can you share the PCB layout in this article? Can this circuit be used to increase an audiot input from a Hz up to 50 KHz?

Such PS is feeding both circuits in parallel.

The labels are correct, but the color coding is swapped. No you dont need to learn c language…. Classified was meant to be class a and water energy was meant to lj386n-1 wasted energy Reply.

I took a lot of time to see. Notify me of follow-up comments by email. Rajesh on September 22, at 4: Thanks to circuit basics. Florence on October 24, at 6: Built this one today, in stereo set 1 for right channel and 1 for left channel. I use a 12V supply and a pot meter to attenuate the input signal to something below 0.
