ADR1399 unobtanium ?

[deepfryed]

I wanted to build a small voltage transfer standard using ADR1399 (more as a learning exercise) and since the eval board seems affordable I thought I'd buy one but it seems the reference and eval board are both unobtanium. Anyone know if this is still being actively distributed ?

200+ in stock.

mouser.com show a stock of 234 ADR1399KEZ SMD references at € 21,22 each. It's not an evaluation board, but in my opinion that board isn't special anyway.

Edit: They show an evaluation board image but it's the SMD part only. Why not use a LTZ1000? Boards/designs are "everywhere".

Thanks missed it, I'll wait a bit for the TO-46 package

The availabilty for the TO46 version was pushed a bit in the past. So I would not bet on the current estimated date.
The 2.5 weeks or so may still be worth waiting.  To a large part the older LM399 can be used as a drop in replacement for first tests if really needed.

eeeks, I just ordered the TO-46 eval board. The customer support said they will have 7 in stock in August September. Fingers crossed.

I wonder where all those TO-46 versions go.. Could it be somebody is hoarding them as a collectable wine?

Same to me, I asked ADI for samples about 2 month ago, but only LCC versions have been available at that time, so I got 5 LCC types ...

The delivery date pushed out bit by bit does not look like someone buying them all, but more like a small problem with the production. The TO46 case is not that common and may well use old machines.

The last time I asked ADI for samples, they said nope piss off  :'(

The only reason I'm interested in the TO46 package is to use a socket, so if I stuff up the design I can reuse the reference without destroying it. Also, I've never used a LCC package and wasn't sure if it needed special handling during reflow / soldering.
