AD5522 Eval Board idle temperature

Hi,

 

My customer noticed that the AD5522 Eval Board run hot when idle(no load ,output disable) ca. 70°C

 

From the reference design, ADI does not mention any heat sink required .

Is this typical? I doubt that we can achieve the spec at that temperature.

Where can I get the thermal characteristic for the chip.

 

Thank you.
