REF3212-EP: NRND?

Adam Daluga

Part Number: REF3212-EP
Other Parts Discussed in Thread: REF3220-EP, REF3225-EP, REF3230-EP, REF3240-EP

Hello,

These parts are shown to be –EP versions available (per TI doc sgzt005a.pdf and http://www.ti.com/pdfs/hirel/mltry/EP_Orderable_Release_List.pdf)

REF3212-EP

REF3220-EP

REF3225-EP

REF3230-EP

REF3233-EP

REF3240-EP

But ECIA search of those numbers has notes from Mouser and Digikey that they are not available nor recommended for new design.

Which is correct?

If they are NRND, why is that the case and could you recommend some replacements?

Thanks!

Hello Adam,

This may be a mistake, but I have to verify. This could take up a week to get you answer but I hope to get something sooner than that.

Hello Adam,

The REF32xx-EP is marked not recommended for new designs because the output could come up to the incorrect voltage under certain power up conditions.

We currently do not have an exact replacement. The best part would depend upon your application needs.

Here is a link to TI's list of voltage references. You can sort on if you need a shunt or series reference, output voltage, temperature range and rating (EP, automotive, mil, etc.)

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
