Hi,
I am considering the AD9432BSTZ-105 (52-Lead Low Profile Quad Flat Package).
How much is the value of ΘJc of this IC?

Hi Yuya,
Thanks for your interest in AD9432.
For the 52-lead LQFP, the data sheet considers only the thetaJA since it determines the thermal characteristics of the package as a whole. The thetaJC is part of the thetaJA. Please see the tutorial note below. Hope this will help.
