Temperature testing with AD9081/2 eval boards and ADS9?

I am interested in running some temperature testing at hot and cold with the AD9081 eval board (EVAL-AD9081) and the ADS9. I didn't see any documentation listing out the absolute max of the eval board and ADS9 -- are the temperature extremes limited by the AD9081 and FPGA on the ADS9? Are there any suggestions from ADI to follow?

  • Hello,

    Both boards were designed to operate around ambient temperature hence putting boards in a temperature chamber is not an option.  

    A crude way of 0perating near the higher end of the die temperature range may be possible when using one of the high power modes when all 4 DACs and ADCs are used near the upper end of their sample rate where power consumption exceeds 10+W.   One can remove (not install fan) to see what the die temperature can get too for that particular mode case.  If one needs to reduce temperature get to near 120 C max die temp can add a heat since and perhaps some slight airflow to lower it.

    The better method should you have this capability is to have thermal conductive plate/heat sink that makes contact to metal lid of BGA package such that the device temperature  can be controlled by measuring the devices die temperature and adjusting the heat/cooling plates temperature.
