I wanna make an amplifier use for 6 spkr. Sample maps can be found in the internet if you are interested in building your own map although 458d diagrams […]. Yeah, it is pretty good, right? A dual potmeter allows you to connect both left and right channel on one potentiometer. I enjoy seeing constructed circuits.

No need to simulate.

Pls oyvind,help me here also i dtaasheet download your book sooner by grace can you provide me with a schematic of 4 stage transistor 2. I want to try making a portable audio amplify for devices like cellphones, mp3 player, etc. Is the layout drsignes to be used with a double sided copper board.?

Part and Inventory Datwsheet. Try a aluminum foil shield to check for external signals that show up as noise. Dec 24 dataheet, 2: CMOS Technology file 1. Is there a way i can link them up together? Dec 248: I am not a HiFi […]. But not more than it can handle.


I found various completed circuits out of hi-fi systems and portable radios. Hey, The design I created was double-sided. So for the stereo amplifier you need a dual pot. Can i use 25v capacitor???

Oyvind, I manage to make my amp work but the problem i am facing now is the output volume is too low ,can you please help me? Another problem I encountered is the TEA chip seems to be a pretty old version and many electronic shops are out of stock. I tried replacing the capacitor but nothing happened. Are the potentiometers needs to be a Dual Potentiometer 6 pins or can I use 3 pin potentiometer?

I have just finished asembling the bridge version and I am impressed of the quality and the power of this IC! This is a really cool thing!

Same thing applies to C7, C12 and C8. Look 3 small pictures for standard pinouts. Hope you can help Thank you.

Thank you so much for the reply! If you love building things with electronics or would love tocheck out Ohmify. ModelSim – How to force a struct type written in SystemVerilog? Thanks for your help. Last edited by kak; 26th October at Please don’t make requests for help in private using PM.

Choosing IC with EN signal 2. I have purchased W sterio amplifier datasyeet USB and mic-2 kit i want to understand bass treble and volume wiring in 6-pin pot. On the satasheet side, you should use a dual potentiometer. Yesall normal types Point for measuring output signal with voltmeter or scope. Check the datasheet of your potentiometer to find out the pin configuration, then match that with the diagram above.


Probably a dual op amp: I was wondering why that was there, but I just assumed it was a separate application entirely because of the name!

There could be noise in the incoming signal. Synthesized tuning, Part datqsheet How can I connect the two inputs to my laptop if I build this on a breadboard? When i connect the one datashert the other, a lot of sound disipates or alot of static comes through, giving me the idea that one or the other is getting too much power or drawing too much.

Also, I do not seem to be able to make the LM specs give me hints on how to do it. Losses in inductor of a boost converter 9. FYI, ive lost 4 radios in 3 months through crime and im done buying new radios. Should I just use a mono amplifier with similar specs as the tea?
