I am trying to create a simple R2R DAC, maybe 8-16 bits.
I want to be able to that type of DAC inline to a headphone line.
Since the an 8 bit R2R DAC will need 8 pins, how exactly do I wire up a TRS connector to that?
Do I have to put an analog to digital converter inline first?
3.5mm TRS analog audio player output -> [create analog to digital output] -> [apply the digital signal to my 8bit DAC] -> output to 3.5mm TRS analog
