THERMAL CONSIDERATIONS
The AD9238 LFCSP has an integrated heat slug that improves
the thermal and electrical properties of the package when locally
attached to a ground plane at the PCB. A thermal (filled) via array
to a ground plane beneath the part provides a path for heat to
escape the package, lowering junction temperature. Improved
electrical performance also results from the reduction in package
parasitics due to proximity of the ground plane. Recommended
array is 0.3 mm vias on 1.2 mm pitch. θJA = 26.4°C/W with this
recommended configuration. Soldering the slug to the PCB is a
requirement for this package.
