Maxim Integrated Products introduces the MAX9700B highly efficient, filterless class-D audio amplifier. It meets FCC Radiated Emissions Standards without the need for an output filter or ferrite beads. This results in a low-cost, ultra-compact, highly efficient audio amplifier requiring very few external components.
Weighing in with SAR Converters
Articles 11/3/2003 Post a comment
In the world of analog-to-digital converters (A/D converters) there are several designs used to convert analog signals to digital. The successive approximation register (SAR) A/D converter is one of the most popular architectures because of its excellent resolution, low power, and its small package size. How does the SAR converter achieve superior features?
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.
