Digitally Controlled Volume, Tone IC ??

[mcs]

I have a few comment for the board layout. You should switch the connections on the 100nf decoupling capacitors to make the distance between the chip and the caps as small as possible.

You should also add decoupling capacitors on the digital supply, as shown in the PGA2310 datasheet.

You can see my board here: http://electronics.dantimax.dk/Kits/Foto/ChipVol1-3.495_400.jpg

The 100nF digital decoupling cap is on the solder side.

Hello

Nice kits, but expensive. Of course you can't share any thing.

Of course you can't share any thing.

Isn't that what I just did? 🙂

My schematic is available at the website, where you can also see the board layout - I don't think I have to share more than that... 😉

Best regards,

Hello

Good luck with your kits 😉

hi

metal:

thanks for the comments.
i will change the connector for the lcd and add some caps in the 5volts supply.

mcs:

thanks
i will switch the connections of the decoupling caps.



anymore suggestions?

Hello

Nice PCB, well done, I don't think you have to add modifications any more, it is good for now, coupling caps, LCD connector....

BTW, please create PDF files for PCB layout, schematic, components overlay, and silk screen.

Thanks

Nice work guys.
What about adding an input buffer,as this is what the PGA datasheet has to say....... "It is important to drive the PGA2310 with a low source impedance. If a source impedance of greater than 600Ω is used, the distortion performance of the PGA2310 will begin to degrade."
Please see here for an implementation...http://www.mhennessy.f9.co.uk/preamp/analogue_research.htm
And yes if you could add code for remote control,would be just great.
Keep it going.
Cheers.🙂

new pcb layout

hi

here is the new pcb layout.

 

[hau]

here is the silkscreen. its in word document

 

[hau]

here is the copper side.the file was spilt into two parts. so you need to download them to open it.

 

[hau]

here is the second part

 

[hau]

for thosed who are interested. here is the ultiboard file of the project.

 

[metal]

Well done 🙂

Thanks HAU.

Can you please submit a file in PDF format containing of full schematic, PCB, bill of materials, and Silkscreen.

Regards

hey guys, for those that are waiting for PICS chips from me. Microchip only allows me to snag a few a week so its gonna be a little bit longer then i thought.

Hi, sorry for the previous post. Well I am a student doing a Digital Hearing aid project. I am using a PIC12F683 microcontroller(With no I2C master function) together with a TDA7316 digital controlled Equalizer. I can't seem to make the 2 devices communicate with each other. Is it possible to do I2c communication Manually? and if so, does anyone have any useful asm source codes? Thank you so much.

I certainly hope you're not abusing their sample program- that's the sort of thing that screws things up for the rest of us...
