Gain Calculations
The ideal mapping of input voltage to output digital sample is defined as follows:
Figure 34. Gain Calculations
In general, the mapping function is:
S = G * V + C
Where V is input, S is output, G is the slope, and C is the y-intercept.
Nominal Gain G0 = 65535 / 4800 = 13.65mV-1
Nominal Offset C0 = 65535 / 2 = 32767
4.6.3
Offset Calculations
The ideal mapping of input voltage to output digital sample is defined as:
Figure 35. Offset Calculations
In general, the mapping function is:
S = G * V + C
Where V is input, S is output, G is the slope, and C is the y-intercept.
Nominal Gain G0 = 65535 / 4800 = 13.65mV-1
Nominal Offset C0 = 65535 / 2 = 32767
