Equation for OCT Variation Without Recalibration
The definitions for the equation are as follows:
•
•
•
The ROCT value calculated shows the range of OCT resistance with the variation of temperature and VCCIO
.
RSCAL is the OCT resistance value at power-up.
ΔT is the variation of temperature with respect to the temperature at power up.
