I tried to evaluate EVAL-ADR9009 on ZCU102 Rev1.1 board. I connected to device and tried to evaluate it. But after a few minutes the temperature of the Eval-ADRV9009 reaches 85-90 celciuc degrees(Even if no complicated process is done). Is it normal? If not, why is the problem caused?
Thanks in advance
I'm also having the same problem. Any help would be appreciated.
ADRV9009 dissipates typically around 3.5W of power and you will notice substantial heating on the exposed die portion . Hence the Top portion will heat up and under normal lab conditions a heat sink is not required. For custom design or where operating temperatures are higher we recommend a heat sink as shown in datasheet.
When you say 85-90 Deg C , Is it measured or a rough estimate ?
I measured the voltages and temperatures via IIO Oscilloscope. Here is the output.

Actually it goes up to 90 degree celcius and I'm running it at room temperature (25 degree celcius).
When both the transmit chain and receive chain are operating, the temperature goes up to 90 °C.
This is normal.
