8-Bit MCU With Dual ADCs Comes In Under Two Dollars
Small, low-cost, 8-bit microcontrollers with analog support are ideal for white-goods, mobile, and security applications. Philips Semiconductors' 12-MHz, two-clock, 8051-based LPC935 houses a pair of analog-to-digital converters (ADCs) in addition to...
Lamp Half-Bridge Driver Chips Boost Efficiency, Need Fewer Parts
A pair of half-bridge driver ICs raises efficiency and slashes parts count in controllers for compact fluorescent lamps (CFLs) and low-voltage halogen lamps. These chips from International Rectifier are based on the company's proprietary high-voltage...
8-Bit ADC Chip Runs At 250-Msample/s, Cuts DNL To ±0.25 LSB
In test instruments like digital oscilloscopes and network analyzers, analog-to-digital converter (ADC) differential nonlinearity (DNL) is critical to providing accurate displays of small input signals. Analog Devices' AD9480 8-bit ADC runs at 250...
Single-Chip Analog Front End Launches ADSL2+ Modems
With the global boom in DSL broadband services, highlighted by a 41% spike in the U.S. alone last year, carriers are looking to boost DSL speeds to compete with cable companies. Current ADSL rates top out at about 1.5 Mbits/s, suiting them for...
Fast, High-Resolution ADCs Attuned To Software-Defined Radios
More basestation manufacturers are moving to software-defined radios (SDRs), which permit multiple bands and standards to be handled with fewer transceivers. SDR receivers use digital signal processing to sort out the signals and perform the...
Analog/Power: 16-Bit ADX Muxes Up To 16 Channels In Less Than One Conversion Load
A 16-bit delta-sigma analog-to-digital converter (ADC) easily multiplexes eight differential or 16 single-ended channels thanks to a settling time that's shorter than the time for a single conversion. The LTC2439-1 joins the same-pinout 24-bit...
Analog/Power: One-Chip Video-Signal Conditioners Handle Cable/Camera Variations
For those security and process-control systems that employ multiple TV cameras, the MAX754x video-signal conditioners will find themselves between the video source and a switcher. They restore the dc level of ac-coupled video inputs, correct for...
Mixed-Signal Process Delivers EEPROMs To Analog ICs
A process collaboration deal between AMI Semiconductor and Intersil Inc. has yielded a mixed-signal process that incorporates electrically erasable memory with no extra process steps. The process can be used in systems with voltages as high as 20 V....
Hybrid 18-Bit ADC Runs At 1 Msample/s
With so many new monolithic data converters announced every month, it's easy to forget that hybrids still dominate certain markets. For instance, Datel's ADS-953 subranging 18-bit analog-to-digital converter (ADC) achieves a 1-Msample/s rate. But that...
ICs: A Good Year In 2003, A Better One In 2004
Total IC shipments should grow by nearly 18% this year, with revenue growth slightly exceeding 20%. This follows a very successful 2003, when shipments grew by 14.9% and revenue increased by 16.1%, thanks to the first increase in average selling price...
Inside The Industry: Nanotechnology
Ongoing R&D programs in nanotechnology promise to increase the efficiency in traditional industries and bring radically new applications through emerging technologies by 2015. Here's why: Half of the newly designed advanced...
Tomorrow's Winners: Nanotechnology
The U.S. National Science Foundation (NSF), a strong supporter of nanotechnology, calls it the next industrial revolution. Most scientists and engineers view it as a vastly more powerful technology than any they've ever seen. Billions of dollars are...
Analog Means Never Having To Say "You're Obsolete"
One of the amazing things about the world of analog is the huge depth of product lines offered by the market's leading manufacturers. Just as noteworthy, product obsolescence issues are real and important, as outlined in Ron Schneiderman's cover...
Managing Product Obsolescence—Now You See It, Now You Don't
When Allen-Bradley's Electronics Division phased out production of all of its electronic components in early 1997, it notified customers which products it was no longer supplying, including part numbers. On top of that, the company recommended...
Ultra-Compact DAC Packs A Performance Punch
The AD5641 NANODAC is the first in a family of very small digital-to-analog converters (DACs) with high-performance features despite their small package size. Available in a compact 2- by 2.2-mm SC-70 package that consumes 70% less pc-board real...
Analog & Power: Four-Channel, 24-Bit Audio DAC Brings 118-dB Dynamic Range
Designed for professional audio applications, the four-channel, 24-bit PCM4104 digital-to-analog converter (DAC) comes with a 118-dB dynamic range, −100-dB total harmonic distortion, and a sampling rate of up to 200 kHz. It uses delta-sigma...
Analog & Power: Transformer-Less Dimming—A Breakthrough For Ballast ICs
A phase-control loop and half-bridge driver for fluorescent lamps are included in the 600-V IR21592 and IR21593 dimming ballast ICs. Both offer a comprehensive set of protection features, including dimming ignition detection and brownout and...
Tiny PGAs Pay Off Big In Data-Acquisition Systems
Too often, even though we have a great analog circuit design, the system specification changes before the product goes into production. Programmable-gain amplifiers (PGAs) can provide the adjustability needed to deal with such last-minute changes....
Broad IP Provider Adds Free Mixed-Signal/Analog Portfolio
Known as a provider of digital IP blocks, Artisan Components now offers a portfolio of mixed-signal and analog intellectual-property (IP) blocks within its Access Library Program. The new IP blocks are available to designers free of charge....
Analog & Power: Triple High-Speed Amplifier Drives Component Video Lines
The ZXFV203 triple-channel video amplifier is characterized for loads of up to 400 pF when driving component video lines. Maintaining an output of 3 V at a 40-mA load current, the amplifier can drive multiple lines. The current-feedback device...
