The VDD dependence of the ambient and object temperature is 0.6 C/V.
Example: As the devices are calibrated at VDD=3V the error at VDD=3V is smallest one. The error in ambient
channel is directly transferred as object channel error (see Figure 23 bellow).
In order to compensate for this error we measure supply voltage and by applying following equation
compensate the result.
