AD820 Junction temperature

Could you  teach me about the junction temperature of AD820 because AD820 datasheet does not describe the junction ?


I think that the junction temperature is 150 degree celcius  as other parts and is it correct ?


Datasheet describes the internal power dissipation at absolute maximum rate.

These are  below and I think that these are defined at 0 degree celcius.

But, maximum junction temperature is 160 degree celicus at SOIC.   ( 1.0W  *160 degree celcius/W) .

So please let me cralify the junction temeprature of AD820.


Internal Power Dissipation at datasheet
8-Lead PDIP (N) 1.6 W
8-Lead SOIC_N (R) 1.0 W
8-Lead MSOP (RM) 0.8 W
