HI All.
I am building a audio interface for my microcontroller, PSoC5. Problem is audio is transmitted through mini jacks in the range -2V to +2V and my PSoC5's ADC can only measure 0-5V.
So I have to raise the -2 to +2V to my ADC range! further more I assume that some kind of AC coupling is nessesary?
Next I need to output the audio to a mini jack again - same problem but the other way around using the microcontrollers DAC?
I come up with some suggestions, but I dont know if it's right, so pls help
Here is my suggestion:
**broken link removed**
And here is the problem described in picture:
