Minolta Dimage X: a different view on optics Teardown 5/27/2004 Post a comment Electronics integration continues to reduce camera form-factor and cost though a clear partitioning of digital and analog functions suggests little technical or economic benefit from combining disparate functions into a common IC process. Sometimes the road less-integrated provides an optimum balance of function, design risk, and cost, particularly when it comes to mixed-signal systems, writes David Carey in this installment of Under The Hood " Analog Edition. That doesn't mean there isn't a lot
Class-D audio power amplifiers balanced just right for small LCD TVs Product News 5/26/2004 Post a comment Providing liquid crystal display (LCD) TV manufacturers with the feature set required to meet high efficiency audio demands, TI announced two new stereo Class-D audio power amplifiers for 17 to 23 inch LCD-TVs. The two new devices feature efficient Class-D operation, driving up to 10W of continuous stereo output power with no external heat sink.
Dialog, Intel sampling combo for mobile devices News & Analysis 5/26/2004 Post a comment Dialog Semiconductor Plc has started sampling a tightly integrated system level power management IC that in a single CMOS device supports both a communications processor and the Intel PXA27x family of applications processors.
Intersil taps AMI Semiconductor's memory technology News & Analysis 5/26/2004 Post a comment AMI Semiconductor Inc., a designer and manufacturer of integrated mixed-signal and structured digital products, has been selected by Intersil Corp. to help design analog ICs at the sub-micron levels for Intersil's consumer, computing, industrial and communications products. From Singapore, Tony Santiago picks up the scent.
Flexible PWM controller fits IBA bill Product News 5/26/2004 Post a comment National Semiconductor positions its LM5033 as the first fully-featured 100-volt DC/DC pulse width modulation (PWM) controller for meeting the needs of modern intermediate bus architectures (IBAs). "The introduction of the intermediate bus is an inflection point in the evolution of distributed power architectures," said Paul Greenland, marketing director for the Power Management group. "Customers expect the next generation of intermediate bus converters to be flexible and efficient without sacri
Modern serial buses demand sophisticated level translation News & Analysis 5/26/2004 Post a comment Electronic design has changed considerably since the days when TTL and 5V CMOS were the dominant standards for logic circuits. The increasing complexity of modern electronic systems has led to lower-voltage logic, which in turn causes incompatible input and output levels for the logic families within a system. It's not unusual, for example, that a digital section operating at 1.8V must communicate with an analog subsection operating at 3.3V. In this article from Planet Analog magazine, a Maxim e
In hot market, only reliable rad-hards need apply News & Analysis 5/24/2004 Post a comment The market for radiation-tolerant FPGAs is heating up as chip vendors roll out new devices intended for military and aerospace applications. But so too is the level of scrutiny they must endure to prove that their parts can work reliably under the harshest conditions.
