Military specs ICs are generally wider operating temperature range, higher frequencies (what else...). So, what physical differences a mil. spec ICs have compared to an ordinary one? What makes an IC, a mil spec IC?
Depends on which mil spec you are looking at. Usually the packaging is much higher quality for a start: ceramic packaging or a hermetic metal can, some shielding for rad hardened devices etc, stronger casing for higher G-forces ratings.
Wider temp ranges mean thermal expansion will be more of an issue which is also a package design issue. Noise of plastic encapsulated devices can also be higher than metal can units from surface contamination of the active device element. So for a start I'd say the packaging would be a major consideration of mil-spec components.
Mark, Thank you..
