Pls advise the case temperature of below ADI devices:
ADG5404BRUZ; ADG1406BRUZ;ADG442BRZ;

 

For the switch/multiplexer parts the max case temperature can be calculated as
follows:
Tc = Tj - Pd x Thetajc

Where
Tj = maximum jn. Temp
Pd = max power dissipated
16 Ld SOIC Thetajc = 42.9°C/W (Standard 2 layer board)
16 Ld TSSOP Thetajc = 27.6°C/W (Standard 2 layer board)
28 Ld TSSOP Thetajc = 14°C/W (Standard 2 layer board)
