Die Temperauture Measure in the ADUC7023

Question asked by Teddy on Oct 18, 2011

Dear sir,

 

I calculated die temperature of 7023(32-Lead LFCSP) and used the following formula:
T − TREF = (VADC − VTREF) × K

T-25 = (VADC-1369)×0.2262

The result is 99°C.-102°C.The the power dissipation of our module is below 1W. So the die temperature is so High.

Would you please give me some advise?Thanks a lot.

 

 

Teddy
