Just wondering if I am crazy, but it seems like something is trying to drive the unbuffered pins on my board. I am trying to use RLE on group 0 and enable all groups for more time, but when I ground the unbuffered (group 2,3) pins to ground, the LDOs get hot and I still get noise on the inputs. Is there something driving these pins? I measured about 1.6 volts on all of them.
