Maxim IC frustration - hard to find components

Although the MAX5204 has only one package style, you still have
eleven different part-number choices. Pity the poor purchasing
officer. http://www.maxim-ic.com/parts.cfm?p=MAX5205 Sheesh!
There's AEUB, BEUB, BEUB+, AEUB+, AEUB+T, and ACUB. ACUB+, ACUB-T,
EUB-T, AEUB-T, and BEUB+T. We have + and - for RoHS status, T for
tape-and-reel, A and B for linearity, plus E and C for temperature
range. http://www.maxim-ic.com/qa/info/naming_conventions/

Choose carefully. It's enough to make one's head spin.


I like the way TI's web page tells us how many parts are available
in each of the various package and processing versions, plus they
tell us what's in the manufacturing pipeline and how far out it is.

Good to see you around again Win.

I have pointed out the difference between Max and TI in excruciating
detail (simply because TI has decided to directly compete with Max)
with the point that this is what Max has to do to survive.

I have been convinced by TI (well, by the FAEs) to do a 100% TI power
solution in my latest product because they are **guaranteeing**
delivery (based on my forecast) of the parts required. TI are deadly
serious about their entire business line, and think nothing of shipping
me an EVM that normally costs $100 for nothing because I *might* design
that part in. In fact, I had to talk to the FAEs (here in the UK) and
ask them not to send EVMs unless I asked because they were arriving at
the rate of 2 a week

Speaking of that, anyone in the UK (Graham and John I know of) who
wants EVMs that are now surplus to me, but interesting to them can have
them. I'll post a list Monday. Free to good homes in the UK. I am sure
TI would approve; their parts will be in front of more people .

I often call them inquiring about such and such a part because it *may*
be interesting, but I am not committed to even thinking further about
it - I am merely exploring possibilities. They take this as a possible
design win and **send me an EVM** even if I never use it. They care not
if I use it; they care that **I have the EVM and I can see their part
in front of me**.

But such things show the differences in the view of the companies; TI
(and AD, National, On, lots of others) want me to design their parts
in, and understand my concerns. I wish Max did.

Cheers

IN CASE YOUR PROBLEM ISN'T SOLVED YET, TRY THESE TWO WEBSITES TO SEARCH
FOR YOUR DESIRED COMPONENTS

WWW.ALIBABA.COM --- ITS AN ECOMMERCE WEBSITE LIKE EBAY.COM WITH FREE
SIGNUP, JUST POST YOUR NEED AND WAIT TILL YOU GET RESPONSE FROM HUNDRED
OF MEMBBERS... I USED THE SAME WEBSITE TO SEARCH A COMPONENT FROM
PHILIPS SEMI AND FOUND AND FOUND IT CHEAPLY

WWW.HKINVENTORY.COM --- POST YOUR NEED HEAR AND MANY (HOPEFULLY) WILL
CONTACT YOU IF THEY HAVE THE REQUIRED PARTS... THEN ITS UPTO YOU TO
MAKE A DEAL WITH THEM!

BUT BE AWARE OF FRAUD CASES AND CAREFULLY DECIDE BEFORE MAKING A BUYING
DECISION

THERE ARE MANY CASE OF COUNTERFEEET MAXIM IC IN CHINA AN SHENZONE. BE
CAREFULL AN D MAXIM WORN OF THIS PROLLBLEMS ON THERE WEBSHITE ALREADY.


Best regards,

Hello John,

For the UPU? A hoopoe!

http://www.birdsofbritain.co.uk/bird-guide/hoopoe.htm

Pretty. We don't have these in the US. But lots of humming birds and a
kind of woodpecker with a red cap. These woodpeckers peck so hard that I
am sometimes tempted to throw them an aspirin for the headaches they
must endure.

 

[John Larkin]

Are you all set now, John, or should we s.e.d. folks be
sending you the samples we ordered as they come in?

Hi, Win

The parts are reported to be going through customs and we're due to
get them on Monday. But we'll need more eventually, so if you've
acquired any for us, send as many as you want to part with and I'll
pay the going rate, or email you our inventory list and swap for
whatever exotic goodies as may appeal to you. Or buy you beers (does
two per DAC sound fair?) next time you're in San Francisco.

Thanks, everybody.

John

I did not make it to the office, so I'll have to do this next week. I
truly appreciate (as should Rebecca) your offer to make this happen,
but my point is you should not *have to*. I have found errors in
datasheets from all the major vendors; some major issues, some less so,
yet I always report them, lest others have a problem. The vast majority
take the report in the way it is offered; an honest statement of a
simple error to be corrected, or for myself to be corrected in the case
I missed something in the datasheet (that's happened, of course

I remember a time when Mot SPS actually offered a bounty on material
datasheet errors (some 20 years ago now, if memory serves).

Once I actually get to the office, I'll dig out the original email
thread.

Cheers

No problem, as it seems to have been screwed up for years. ;-) Just
post it when you get it, then for fun we can post when it gets fixed.
Well, in a different thread. ;-)

[1] OK, a jillion is 10^j, and thus purely imaginary.

this being usenet and all there's always atleast one pedant.

It's more complex than that.

10^j
= exp(ln(10) * j)
= cos(ln(10)) + j * sin(ln(10))
approx = -.6682 + j * .07439

Pretty. We don't have these in the US.

The south coast of England is the extreme north-western limit of their
summer range. They are widely distributed across south and central
Europe.

But lots of humming birds and a kind of woodpecker with a red cap.

Many woodpecker species have red caps.

These woodpeckers peck so hard that I am sometimes tempted to throw
them an aspirin for the headaches they must endure.

Their brains are protected by some very clever natural engineering. This
will probably be copied for the inertial dampers for the star-ship
Enterprise.(;-)
