I'm using MAX6126 with output voltage of 4.098v and it outputs that voltage - verified with precision multimeter.
The +Vref is tied to MAX6126 output and +Vref is tied to GND. So this is why I have ADCON1=%10000001
When I tie RA0 directly to MAX6126 output, the raw output reads 1023, when I connect it to GND, it reads 0.
