Compensation Steps:
1. Correct for Offset
2. Take absolute value of the offset corrected ADC value if negative—the gain correction
3. Multiply by Gain Correction Word. If in DIFFERENTIAL mode, there are two gain

Based on the sign of #2, use the appropriate Gain Correction Word.

the factor is positive and is left unchanged. If they have differing signs, then the factor
is negative and must be multiplied by -1.
