I also found this, by Tiktak, which is a variation of the manufacturer's test circuit (adding a regulated power supply). I downloaded his pcb pattern, but have had a bit of trouble constructing the circuit. My eyes aren't what they used to be, and the board is a little to crammed for my tastes. Besides, I'd rather use screw terminals than RCA jacks for the board.
So I created an Eagle project to design my own variation (wutrh the parts spread apart for easier soldering). I also added a header so I can plug in my si4703 FM radio breakout board and rount its audio output to Input 3 of the 7313.
Since I've never used Eagle before, I was hoping one of you nice folks could look at my schematic and board layout. I've also included the TDA7313 manufacturer's test circuit, and Tiktak's schematic and board (much more polished than mine).
Note that I haven't added the ground plane yet for my board, as I'm frankly not sure how to do that.
Thanks as always for any or all help and advice.
