Hi all,
I've built the active volume control as shown in TI's TIDU034 app note. After some initial hiccups I got it working, but my output is monophonic. Any idea where I should start looking ? I've triple checked the schematic and my wiring.
EDIT: Derp! Turns out the potentiometer I've been using has pin 1 of both decks joined - the leftovers from its last duty as a standalone volume control ! Two seperate pots and now it sings perfectly!
How would this circuit fare as a headphone amp? With, for example, an OPA551 as the output?
