ADN4600 thermal characteristics

Q

what are the package thermal resistances for junction-ambient, junction-case
and junction-board for ADN4600 in 64 pin CSP? The ADN4600 datasheet does not
give this information and the thermal datasheet on ADI website only provides
thermal data up to a 48 pin CSP 7mmx 7mm package.

A

These are the specs for ADN4600 64 pin CSP that I received from our
packaging engineer:

Tja = 22 C/W
Tjc = 1.1 C/W
Tjb = 13 C/W
