As ever, when ordering parts for an instrument, at least one part won't be in stock. In this case, it was the OPA134/2134PA op amp. Neither Digi-Key nor Mauser had them (lead time 27 weeks).
The last time this happened, TI was going through a RoHS cycle. But what is going on now? Every one of the Burr-Brown op amps that TI has continued in production seems to be unavailable - even the instrumentation amplifier line.
TI lists them as in production, but with no stock and lead times of 20 weeks. Only Rochester Electronics, a job lot dealer in obsolete devices seems to have stock.
Any guesses? None of the skims through the industry news has anything to say. If TI is going to just drop them, that is a big hole in the really useful and affordable op amp selection.
