I did reach out to those suppliers and hadn’t heard back yet. In my experience, they don’t rush to accommodate such small orders (which is understandable). I thought someone here might have one or two extra they would want to part with.[but they seem to be backordered with all of their distributors] -- I have provided you with 3 sources that have either hundreds and/or even thousands of the -- INA137PA (DIP) -- IC in-stock and their URL links to purchase them.....EVEN RIGHT HERE IN THE U.S. of A.!!! Is there a problem with you contacting any of these particular suppliers to buy what you need? I don't understand.....
(NOTE: I once worked as an "Electronics Purchasing Agent" buying millions of dollars worth of "hard-to-get" parts. So, it just becomes a matter of "knowing" where to look for "obsolete" electronic components).
