You need to see what raw values are being read out of the ADC. If they're higher than 4095, then you've got a problem - Which I'd guess would be a bad ADC.
Passed that . . . voltage = ( raw_value / 4095 ) * scale Where scale = highest possible voltage to be read in. Then of course max voltage on the ADC must not exceed 1.8v, ever. Anyway, I figure you probably know most of this already, but do need to know that raw values over 4095 is very likely going to be bad news . . .
