About AD8599

1. We are using the AD8599 at ± 15V.  When the room temperature is 25 ° C, device temperature  is 80 ° C. Are these normal?

    Hi,

    Can you attach your schematic to verify whether this is in normal operation. Assuming the part is operated at ± 15V supply, ambient temperature and buffer configuration. The products junction temperature should only be around 66degC using the formula:

    Tj = Pd x thetaJA + Ta

    where:

     Tj = Junction temp

    Pd = power dissipation

    thethaJA = junction to ambient thermal resistance

    Ta = ambient temp

    You can learn more about this with this article.
