where have all the OPA2134s gone?

[mazurek]

After months of planning, I am finally ready to build something, but it appears mouser and digikey have no OPA2134s for a couple of weeks.

Anyone know a reliable source to get them?

try OPA2132. It's just a better version of the same thing.

There are other distributors. Check www.ti.com for distributors and their stock.

Did you check with Gengis ? More reliable than Mouser.

All your OPA2134 is belong to us.

No!!1 You guys stole all my op amps.

Called the one distributor listed by TI as still having stock, they are out. Luckily, it appears Gengis can save me. Those 2132's cost double, and needing 22 op amps total means that would have been signficantly more.

I seriously think diyaudio has consumed the worlds supply of OPA2134.

This has been up for discussion before, without getting any answer, but do you have any idea what actually differes between the 2132 and the 2134? They have strikingly similar specs and graphs in the datasheet. Yet, there must be some fundamental difference since they are both on the market and by the same manufacturer.

I've read this page on op amps before. Look at their comments on opa2132/4. It appears 2132 is a slightly nicer industrial version. I bet they're the same thing though, just binned differently.

OK, I have actually read that page many years ago, but forgotten that he had something to say about this. It is not clear, though, if his claim is speculation of if he has got the info from somewhere. Anyway, if he is right it is the same chip and they label the better ones as 2132 after testing, and the rest as 2134. That might explain why Sony bothered to use the 2132 in some of their more expensive CDPs.
