Exclusive to eeProductCenter: Linear Technology Corp. says its 1.8-volt dual and quad operational amplifiers are the first available in a tiny DFN package.
Excuse me, did you say ICs available for 25 years?

Last summer, I watched as the "telephone company" (whatever that term means now) replaced all the poles on our street, over a month-long period. This carefully choreographed procedure was itself interesting, and had more interleaved steps than I expected. When I asked the crew chief why they were replacing the poles, he replied, "it's on our schedule to replace these poles every 25 years, as preventive maintenance."

The IEEE annual International Solid State Circuits Conference in San Francisco this week was a proud and impressive display of devices and ideas. A/D converters--both Nyquist and oversampling types--were the subject of key sessions. Here's a brief report on just a few of the designs presented, all substantiated by real silicon.
Multiplexers operate over wide voltage range

Vishay Intertechnology, Inc. released a trio of precision, low-voltage, monolithic CMOS analog switches that are said to combine a wide voltage range, low leakage, and tight on-resistance matching for precision signal switching and routing.
What happened to the 42V auto?
Articles 2/3/2006 Post a comment
A few years ago, there was lots of serious talk of cars transitioning to 42V supplies, either in addition to, or to replace, the venerable 12V system they have used for decades. Why didn't this prediction materialize? More puzzling, how have the dire problems, that were predicted if we stayed with 12V systems, been avoided?
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
