QWe are performing Thermal Analysis of a Board, we are using the following parts
We have the Theta Ja (Thermal Resistance junction to Ambient)
We need Theta jb (Thermal Resistance junction to Board) and Theta jc (Thermal
Resistance junction to Case)
AWe do not have Theta-JB for any of our parts. Theta-JC is on both the OP284
and the OP296 datasheets.
The OP284 and the OP296 both came out in 1995. We now have next generation
versions of both parts
on newer processes with improved performance: ADA4084-2 and ADA4096-2. I
would not recommend
doing a new design with either the OP284 or the OP296.
