You were right! That was definitely the problem, I had the capacitor on backwards and now that part is fixed!
Unfortunately, now I'm having the same problem with a different part of the circuit. On one of the smaller eval boards, specifically the high pass dual board, the +and- VS's are now drawing current. My -VS is drawing a lot more however, making the DC supply lose voltage whereas the +VS is only drawing about .02 amps (as read on the DC supply). Both the +and- VS are sparking on contact. I suspect the capacitors C0 and C9 because they are positioned directly between REF(connected to GND) and the VS's. And my multimeter can actually measure their resistances (~18Mohms), unlike the same capacitors on the functioning eval board. These capacitors aren't polarized, so I don't think that's the problem, but it seems like they have failed.
My plan is to replace the C0 and C9 capacitors, but I don't want this just to happen again. Is there anything you see that I've done wrong maybe with the op amp, or other connections? I've attached a close up of the problematic eval board.
Any help is much appreciated!
Thanks,
Bryan
