Texas Instruments introduce dual-channel, bipolar-input audio op amp. The OPA1612 offers designers desirable noise and distortion characteristics for clear, crisp sound in applications such as professional audio and broadcast studio equipment. Features include bipolar input which achieves
The Electrical/HVAC Combo Kit from Fluke includes the Fluke 62 Mini Infrared Thermometer, the Fluke T+PRO Voltage and Continuity Tester, and the Fluke 1AC-II VoltAlert Non-Contact Voltage Detector. All three tools are compliant with the 2009 edition of NFPA 70E. The thermometer measures from -30ºC to 500ºC
Resisting noise interference, the PCM-3730I, a 32 channel isolated digital I/O PCI-104 module from Advantech, supports high-voltage isolation (2,500 VDC) on each input/output channel. With an input voltage range of 5 VDC to 30 VDC, the PCM-3730I allows different modules to be stacked together in a small system.
The USB-COM-PLUS family of communication modules from Future Technology Devices provides dual port capability for the RS422 differential and RS485 multipoint differential interfaces. All multi-port modules feature a USB 2.0 Hi-Speed (480 Mb/s) interface, and feature a 5 V output that can provide up to 250 mA.
Google Inc. is testing a new format that is supposed to make reading online stories as easy as flipping through a magazine, a shift that eventually could feed more advertising sales to revenue-starved publishers.
As any video game aficionado knows, it's easy to pop a game into your Xbox 360 or PlayStation 3 and spend hours working your way from one level to the next. Without the hefty console, though, you're out of luck if you want to keep blasting those aliens while away from home. A startup called Spawn Labs thinks it has a solution to this problem.
French legislators vote Tuesday on a pioneering bill allowing authorities to cut off Internet access to people who download illegally, a measure that entertainment companies hope will be a powerful weapon against piracy. The bill has garnered attention beyond France, both from music and film industries struggling to keep up official revenue and from privacy advocates who say it threatens civil liberties.
When lighting applications started using solid-state sources, engineers began to understand the issues in the migration away from incandescent bulbs. It is fairly well known that LED sources lack the IR spectrum of their filament based counterparts requiring thermal management via conduction rather than emission. Driving and managing these solid-state light sources can be challenging
As applications engineers, we are constantly bombarded with a variety of questions about driving high-speed analog-to-digital converters (ADCs) with differential inputs. Indeed, selecting the right ADC driver and configuration can be challenging. To make the design of robust ADC circuits somewhat easier, we’ve compiled a set of common “road hazards” and solutions.
In determining the safety of improbably small materials known as nanoparticles, special properties associated with some of the very smallest particles may be the key, scientists said on Sunday.
Vishay Intertechnology announced a planar transformer designed for switchmode power supply (SMPS) applications, including flyback, forward, push-pull, and half-bridge converters. The Sfernice PLAC 100 is user-configurable with software supplied by Vishay, which allows designers to
With 10 discrete component functions integrated on one chip, the EPCOS ESD/EMI audio filter (CA04F2FT5AAUD010G) reduces parasitic noise and increases audio quality in portable devices. The filter features low series resistance, comes in a 405, two-fold array package, a cut-off frequency of
The FXA series of ceramic SMD (surface mount device) automotive-grade crystals from Fox Electronics feature a frequency range from 6 MHz to 150 MHz. The crystals have standard frequency stabilities from ±50 ppm to ±100 ppm and operating temperatures from -40°C to 125°C.
The LT3050 voltage linear regulator, from Linear Technology, offers low noise operation of 30µVRMS across a bandwidth range of 10 Hz to 100 kHz. The device delivers up to 100 mA output current with a 340 mV dropout voltage at full load. It features a 2 V to 45 V input voltage range, delivering adjustable output voltages from 0.6 V to 44.5 V.
Cyber criminals are increasingly targeting small and medium-sized businesses that don't have the resources to keep updating their computer security, according to federal authorities. Many of the attacks are being waged by organized cyber groups that are based abroad, and they are able to steal not only credit card numbers, but personal information
