IF there is any application circuit for the temperature compensation function of ADPA7002Chip?

IS there any application circuit for the temperature compensation  function of ADPA7002Chip?How can I apply this function?

    Hi LZEVIN303,

    To use the temperature compensation function of the internal power detector, you will need to connect VREF and VDET to +5V through a 100K ohms resistors as shown in the application circuit below. By taking the voltage difference between VREF and VDET you will get a voltage reading that is independent of temperature and corresponds to a certain output power level as shown in Figure 47 of the datasheet. You can use a subtracting op-amp to take the voltage difference between VREF and VDET as shown in the circuit below.
