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.

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...

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.

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.
G4ME said: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.
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...
