Part and Inventory Search. As I want to make it completely portable.

Hello im very new to all of this. I use to make amplifiers from the internet and it makes little hmmm noise when the volume is attached. I need to boost a signal sixfold before I divide it by 6 to send to 6 different destinations. If you have the correct DC voltage in, the circuit is fine as long as the power supply can prove enough current. It was always something that made me hesitate.

Thanks for your quick reply, I tried your suggested solution and yes the noise is still present at lower datashete. Yesall normal types Point for measuring output signal with voltmeter or scope. datashdet

4558D Datasheet, JRC NJM4558D PDF

Should I just use a mono amplifier with similar specs as the tea? How can I buy your textbook sir, for I really neef it. Any clue Oyvind would be really appreciated. I am not a HiFi […]. Look 3 small pictures for standard pinouts. The output goes to the speaker. But if you want more power, datasheft the datasheet for how to connect the outputs in mono-setting.


LM4558 Dual High Performance Op-AmpLinear IC

I wanna make an amplifier use for 6 spkr. ModelSim – How to force a struct type datasheeh in SystemVerilog? Everyone can improve even if they are complete beginners or have built many circuits from before. All the schematic diagrams that I could find seemed to involve lots of hard-to-find components or you had to use it together with a pre-amplifier or some other amplifier stage.

Can i use 25v capacitor??? I cant seem to find any schematics for this chip. PNP transistor not working 2.

For splitting the signal, you can use resistors for basic splitting. Pls oyvind,help me here also i will download your book sooner by grace can you provide me with a schematic of 4 stage transistor 2. Datashee can find one here: Pinout can vary by different types so allways check from datasheet These are the pins in test circuits This dot means that they should be connected.

First check IC type and pinout from datasheet.

Thanks for your effort. Please what should I do. Hi, The input does no go to the speaker. I was wondering why that was there, but I just assumed it was a separate application entirely because of the name!

D/ Datasheet, PDF – Qdatasheet

Check out page 5 in the datasheet for circuit examples: This will make the sound noisy. This amplifier is great to use together with some speakers to get sound on your desktop computer. Turn on power triac – proposed circuit analysis 0. Buy a tablet power supply 5V 2A, for fast charging and check current consumption with a multimeter.


And one more thingi think i should add, I am using USB power supply. Input port and input output port declaration in top module 2.

What is the function of TR1 in this circuit 3. I found various completed circuits out of hi-fi systems and portable radios.

I challenge you to figure it out from the datasheet: But not more than it can handle. Datasueet filtering or to avoid oscillations. What is the diagram software that you used to create these circuit diagrams?

Hey, thanks for the great schematic, I was actually looking to make an audio amp and this one looks awesome! Im only using my phone as the music player. Try switching the inputs and see if this gives you an output on the other channel.

Losses in inductor of a boost converter 9. I am not a HiFi geek, I just wanted to build a simple datashest amplifier that could drive some speakers for my desktop computer. Sample maps can be found in the internet if you are interested in building your own map although the diagrams […].
