I would like to know if AD8622ARMZ is currently in production, what is its expected EOL?
I retired last July from ADI after 10 years w/ the precision op amp group, and know the 8622 quite well.
If I was going to have ten op amps in the lab for breadboarding, the 8622 would be one of them. (along
with the ADA4084) If is a really nice combination of Vos, IB, ISY, GBW, etc.
ADI does have some op amps and other parts that they have been shipping for over
35 years. Analog parts are "sticky". If it's a tight design, there may be some characteristics that are
not measured or spec'ed so a "second source" doesn't work. I found that customers are afraid to mess
with an analog design that is running successfully in production. They don't want to take one of their
designers off a project (that's already late) to qualify a second source.
Now let's do a thought experiment. If you buy 5 million parts every year for the next 30 years, I guarantee
you that ADI or any of the analog companies would be overjoyed to keep makinig the part.
Or maybe there are 50 customers, each buying 100k parts/yr; same thing.
Or 500 customers, each buying 10k/yr. Same thing.
The problem comes in when one customer buys a million parts a year and there are 99 other customers
that buy 100 parts a year. If the big guy stops making that product, you are out of luck. But not really.
ADI gives you one year to place lifetime buy orders and one year to accept deliveries. So if you use
100 parts/yr, you could place an order for 1,000 parts and store them in dry nitrogen and you are covered
for ten years.
If I remember correctly, the 8622 was ramping nicely over the part five years, so I would design it in if I
were doing design today.
I'll send an email to one of the guys in op amps apps for additional comments.
I've put in a request to find out the expected end of life for the AD8622ARMZ. I will get back to you soon.
At this time, the AD8622ARMZ is set to be in production through 2028. This is subject to change based on future demand or product revisions.
Please don't hesitate to ask if you have further questions on the part.
May I ask how you plan on using the AD8622?
