Use Table 10 to determine the OCT variation after power-up calibration and
Equation 1 to determine the OCT variation without recalibration.

Notes to Equation 1:
(1) The ROCT value calculated from Equation 1 shows the range of OCT resistance with the variation of temperature and
VCCIO
.
(2) RSCAL is the OCT resistance value at power-up.
(3) ΔT is the variation of temperature with respect to the temperature at power up.
(4) ΔV is the variation of voltage with respect to the VCCIO at power up.
(5) dR/dT is the percentage change of RSCAL with temperature.
(6) dR/dV is the percentage change of RSCAL with voltage.
