Parameter Trends vs. Temperature
Figures illustrated in this chapter provide information on the experimental performance of the AUIRS44261S HVIC.
The line plotted in each figure is generated from actual lab data. A large number of individual samples were tested at
three temperatures (-40 ºC, 25 ºC, and 125 ºC) with supply voltage of 15V in order to generate the experimental
curve. The line consists of three data points (one data point at each of the tested temperatures) that have been
connected together to illustrate the understood trend. The individual data points on the Typ. curve were determined
by calculating the averaged experimental value of the parameter (for a given temperature).
