I would like to estimate the temperature of the die using the FDA pin of the AD9680. In the datasheet Figure 140, you are only showing the curve for 1.8V SPI, how does the curve change for 3.3V?
Thanks for the help.
The temp diode for the SPIVDD=3.3V has not been characterized as rigorously as the one for SPIVDD = 1.8V. However, here is the data for your use.
