TI new products

Not sure how serious I take that I downloaded the 'datasheet' for the 'AFE8092 Octal-Channel RF Transceiver with Feedback Paths'

Not even a block diagram, and big pictures of ballgrid array but no pin function list. so 4 Giggle samples per second ADCs... (after figuring out what GSPS stood for).

Not usable with that data.

But more and more integration indeed.

Too many pins... Maybe just for thermal...

My opinion dataheet written by complete electronics moron He explains ADC (but everybody doing electronics knows that) but GSPS in capitals is the wrong notation for Gsamples/second. No block diagram is a FAILURE! Why bother to check the rest of the crap blurbs they publish.

Agreed - there's lots of interesting things there.

But can they actually deliver them? That's the big challenge these days.

But sadly no quantity of OPA4322 until into 2023, 1.8 volt CMOS op amp with 20 MHz GBW and 10uS slew rate.

Hmpf! I used that one a lot pre-pandemic, IIRC AD didn't have anything near as nice in the low voltage/CMOS department for the price a few years back.

There was an episode of The Amp Hour a while back, interviewing a guy doings ASICs. He did over 50 designs per year, one guy

More likely they're waiting to see who will order a few million.

I'd go with Gsamples/s. In a sufficiently unambiguous context, maybe GS/s will do. (They wouldn't be talking about the rate of change of conductance in a treatise on ADCs, now, would they?)

'Samples' is the only unit without a universally accepted abbreviation.

Jeroen Belleman

I'm not following the thinking. Everyone I've met is comfortable with the MSPS or even just SPS notation. Why is GSPS the odd duck? Why is S not an accepted abbreviation for "samples"? Because it's not an SI unit? Neither is HP, but in very common usage.

If TI introduces, say, one new part per day, can they support them? Will they still be in production 10 years from now?

I tried to get some support for one TI part. The guy said "that's a Burr-Brown part, nobody knows much about that."

Yes, because there are no units associated with a sample in the abstract, the units being those of whatever is being sampled.

Mathematically, a sample is what one gets when multiplying a function of time by a Dirac Delta function.

Joe Gwinn

And they're still using Burr-Brown branding for their newly-introduced JFETs (JFE2140). I thought that was odd.

And EVERYTING is out of stock. Vaporware for all practical purposes. How do you design something with some part that is "new" and unobtanium at the same time?

I can make a thousand such "new parts" per month, all better than anything else and several times cheaper than existing best parts. The only problem is that those "new parts" don't really exist but who cares?

** A lot of the new parts were described as "automotive". Guess that is a a really big market area for such tech lately.

So designers are specing them for new car designs all over the place. Then the expected stock fails to appear. Hence the shortage of a great many new cars models - if even just one chip is missing.

I thought that was Maxim! lol

If you have to google what GSPS stands for, you obviously have no use for the full data sheet.

MSPS and GSPS is absolutely common.

blafasel.

Oh, you know it all asshole

Its a crap 'datasheet' makes no sense whatsoever, maybe some intern training for sales droid made it Best of luck with it, and you seem to not know the difference between ground penetrating radar and metal coil detectors either.

Lots of things are common that are wrong, like soem of your postings for example.

:-)

Common and have been that for decades of course. When I designed our first HPGe MCA acquisition front end with direct digitizing (

), DSP etc. MSPS was already common, that was late 90-s. And of course you are right that someone who does not understand the term has no use for a complete datasheet, but the lack of a decent datasheet (which I did not bother to look at so I just accept it is crap from what was said in other posts) speaks a lot about the state of the product. Or about the willingness to sell it to anyone, things get worse by the day in that respect...

I guess they're mimicking the financial Industry, now.

It has grown into new, seemingly huge proportions but it is not anything new. Back in 1992/1993 I had designed in a SCSI interface part from a catalog (naive beginner), I think the firms was called Emulex or something like that. When I got the first version of the PCB I had already understood the error I had made (the part had never been produced, not even in prototype quantities I think); so I had to redesign the board with an NCR53CF96, a real part... The first unit (

) had a huge

230 megabytes of a 2.5" SCSI HDD inside, which cost me a fortune (no www to search for bargains, bought it from Apple at something close to $1k IIRC). Shortly after magnetoresistive R/W heads came into being, 2.5" SCSI peaked at 810 MB and among other things made life easier in terms of magnetic field interference compared to life with inductive heads. And forced me into doing ATA, now SATA, into further products...
