Bill, Kash is right about non-rad-hard parts. You are even mistaken that LM158 is designed for the defense industry! Unless you buy bare dice and qualify the whole assembly to meet the Mil Spec, any semiconductor devices have to be hermetically sealed. LM158 is not necessarily hermetically sealed. It comes in plastic, metal can, or ceramic. Both metal can and ceramic devices are hermetically sealed. Then there are three generic grades in terms of reliability: JAN, JANTX, and JANTXV. The `V' in JANTXV means visual. Some qualified experts actually examine the bare silicon dice for visual defects. All these devices may not come from the same wafer, but they are all fabricated from the same process. Time Traveler has never heard of this Bausch-Lomb stuff. Are you making that up or twisting the truth a little bit? Time Traveler
