Large PDN from Analog Devices

This is an interesting list, thanks for posting it.

A very large number of the entries are either replacing package types containing lead with lead-free versions or changes in the reel. What surprises me most is to see that ADI are still selling enough of certain part numbers (AD565 and DAC312 caught my eye, I'm sure there are others) to justify keeping them alive at all. AD565 was a fairly new product when I joined ADI in 1982, and DAC312 was in the PMI catalog when ADI acquired them.

One of my customers subscribes to an end-of-life alert software service. But they're not very good about entering their critical parts into that thing.

We need an IoT so that individual parts in finished products can check the internet themselves, and stop working if they're obsolete.

That leads to the opamp-as-a-service business model.

Many digital types eschew analog parts like op-amps; these should be processed digital data streams. And of course this should be in the cloud. Miss a payment and the op-amp functionality stops working. But we analog types will argue to keep the real local analog op-amp, by adding an enable pin that can be controlled by the cloud's subscription model. Then there will be a DMCA equivalent, to outlaw hacking that control pin.

Don't encourage them, they are already pretty much doing this.

DSO manufacturers will already sell you a code or serial EEPROM for a lot of money, that will increase (really, un-decrease) the bandwidth of your scope. In the Rigol scopes the deliberate bandwidth crippling was doen with an adjustable analog filter, but some of them might use a digital filter.

Danaher corporation (current owner of the Tektronix brand name) went after Hackaday with a DMCA takedown notice for describing how to un-downgrade the scopes. I'm not sure whether that was for a bandwidth un-downgrade or for un-disabling some trigger modes.

Nooooo! I have boxes full of 12AX7s, and I know how to use them!

Payments would be a b-tch. For your hifi you'd be billed by many companies for each & every component 1p/1c at widely varying time intervals.

Luxury! When I were a lad we had to make do with a clockwork amplifier.

The punch line is that one of the comments to the last article points out that the un-crippled Hackaday post is still on the Wayback machine.

I see nothing wrong with that, you got the bandwidth you paid for at a price you were willing to pay, why is how Rigol chooses to deliver that an issue?

-Lasse

Rigol chose to deliver me a scope, why is how I choose to use it an issue?

You chose to enter into a contract for a product _and_software_ of certain specifications. If you changed the contract unilaterally, perhaps they do have a point. IMO (but that's irrelevant, here) - your scope, you can do anything you want to it. Publish the instructions to hack their software and you can be in deep lawyer.

First Amendment? :)

Nope. Try again.

So what? I had cases of 6SN7s :)
