ADA4870 Die Temperature Monitor

Can I use the Thermal Monitor and Short-Circuit Flag (TFL) pin to monitor peak die temperature?

    Good question, given there are process variations with the ADA4870 and semiconductors in general, this prevents the TFL pin from being used as an indicator of absolute die temperature. However, the TFL pin can be used to monitor relative changes in the die temperature. The voltage on the TFL pin varies at approximately -3mV/C.

    I hope this helps.
