Starting a student project, need some input (chip amp + speaker set)

[Sneasle]

here is the input schematic page, it only lets me do one attachment at a time.

The potentiometers have too low resistance. Go for 10-50k.

All capacitors below 1 µF should (and will) be non-polarized, e. g. ceramics for C8 and C11 and MKP for C13-16.

 

[Sneasle]

whoops, yes, you are correct, I forgot to edit those values.

Ya, I know the smaller caps won't be polarized, but I just put em that way. If it irks you that much I'll change it

There is no point in posting incorrect or misleading information.

Either post correct schematics or don't post.

 

[Sneasle]

Ok ok.. sorry... didn't think it would bother anyone, much less get them all riled up.

I've corrected and redrawn it. I hope this gets the warm fuzzies flowing again.....

 

[Sneasle]

here are the fixed inputs.


Nothing is tied to the stby and mute lines yet as I don't know how I want to handle them. If someone has some suggestions, feel free to throw them out.

 

[AndrewT]

go and buy a 3886 and follow the datasheet to get it working on a single polarity supply.
When you have learned how to do that properly and to meet your targets, progress to the complicated version.

 

[Sneasle]

How is a 3886 simpler then this? I just don't understand your reasoning in telling me to go to a 3886 becuase it is simpler when the parts count is higher and it is only a single channel IC.

I just don't get it.
