1  Using Arduino / Audio / 11.5V on PGA2310 audio output on: April 10, 2011, 12:20:53 pm
I have connected a PGA2310 to the arduino as described on http://nospecifictopic.blogspot.com/2011/01/controlling-pga2310-with-arduino.html. I have then added power and audio, and thats it. But trying to connect the amp just gives me a very loud buzz. I measured the audio out lines, and got 11.5V. That cant be right?

Ive attached a diagram of my own connections. What am I doing wrong?

Sorry if this is a really stupid question, but Im new to this and Ive been trying for hours with no luck.

Thanks!

Hi,

I'm currently trying to do the same thing, replacing a normal volume pot with a digital arduino based solution. I haven't seen any schematics of how anyone have connected the actual amp to the PGA2310 and I was wondering if it requires any additional hardware. Or do I just connect the lines and that's it?

Thanks in advance!
