Note:

 

 

 

The ADC-linear characteristic is described by 4 coordinates, based on a two-point equation:

y - P0758 = P0760 P0758 x - P0757 P0759 P0757

For calculations the point-gradient form (offset and gradient) is more advantageous:

y = m x + y0

The transformation between these two forms is given by:

m =

For scaling of the input the value of y_max and x_min has to be determined. This is done by the following equations:

= P0760P0757 P0758P0759
