You could use the lineout pin header which uses teensy GND
I suspect there are implications for distortion and noise, especially for low-impedance load like a headphone - basically this is notThe manual has an application example with the 20 QFN version of the SGTL chip which just puts two 200uF capacitors on each of the headphone amp outputs and then the headphone jack is grounded, the virtual ground is left unconnected. Would this work? And would there be any considerations regarding phasing or distortion? Also, could this configuration have any negative impacts on the SGTL's headphone amp outs?
Capacitors block DC. You choose the caps to be so high in value that the high-pass action is of no consequence (say at 6Hz or so)If it does work, would anyone possibly be able to explain to me why this works? I know this creates essentially a high pass filter circuit on each output, but does that manage to create a DC Bias also? Thank you for any insight you can provide.
