ADC issues

I have two upboards purchased in the past year that are both having trouble with the ADC input. When I put a constant voltage of .7V into the ADC pin and cat the value at /sys/bus/iio/devices/iio:device0/in_voltage_raw', it is bouncing all over the place. I have tested this with two up boards and checked with a multimeter that the voltage is constant. I had no issue doing this on an upboard 2 years ago and am using a cloned image which leads me to believe that maybe it is a BIOS issue.
