The output of the ADC is an 11-bit, signed, two’s complement digital value. The output
generally ranges from 0 to +1023, but offset errors can cause small negative values.
The ADC registers return 13 bits of data, but the two LSBs are intended for compensation
use only. When the compensation routine is performed on the 13 bit raw ADC value, two
