NE5534AN

[sodderboy]

Does anyone have a good source for Philips or Signetics NE5534AN?
I see them on ebay but they are mostly from China and I don't have much trust.

Digikey and mouser both list ON semi as sources for 5534an while mouse says it is obsolete.

ON semi is headquarters in US (az) but manufactures all around the world. 

Those are mature parts to put it kindly.

I think that folks on the interwebs have decided that Phillips or Signetics made the "best" 5534 and people are stockpiling them to service their now-vintage consoles, etc.  I don't know of a source for the brand name chips in quantity and I have never had a complaint replacing one with current production.

or maybe its the typical scarcity premium.

There are modern op amps that spank them on pretty much every measurable specification.

Phillips had a mask exchange agreement with a number of other semiconductor manufacturers. They actually swapped raw manufacturing data with each other so they made identical devices. This was quite common in the early days when there were relatively few op amp types around.

ON Semi was formed in 1999 from the semiconductor division of Motorola and later acquired Sanyo, and most recently Fairchild and has a strategic partnership with Fujitsu all of which is typical of the industry.  Phillips/Signetics semiconductor business is now NXP. There is no reason so suspect ON Semi versions of the 5534 are any different to Signetics ones.

Not AN, but Phillips at least:

Thank you, Ian, for that factual summary of what I surmised to be the truth all along.

The Caen-fire of December 2003 caused production-stop for Philips of these types and might have added some (debatable) myth on top...  :

Interesting to hear about the mask exchange agreement, hadn't heard of that before, at least not for the 553x types.

FWIW, Phillips (two times L) is the screwdriver-type, and Philips (one 'L') the electronics brand. Who knows it increases number of hits when looking for 5534 with one L.

I wouldn't do this.  I would use Signetics or NXP instead......

And I would look for TDA1034(N) (it is the same chip):

Wow, already 11 bucks/pc, I think I should sell some....

The FWIW-suggestion was 5534 & Philips (as TS also mentioned), iso 5534 & Phillips.

Or Signetics indeed, …
but I doubt a legit 5534 from NXP exists. NXP was founded after Philips-production stopped.
(Perhaps a rare/last remaining batch was sold with NXP-markings, don't know)
