A recent engineering design challenge asked FPGA experts to design a “Logic Analyzer in a Day” using off-the-shelf Opal Kelly FPGA-USB modules and its Front Panel SDK. The objective was to showcase the design capabilities of these engineering experts...
This training module from Digi-Key and TT Electronics/Optek Technology provides guidance on managing junction temperature of high-power visible LEDs, including ways to remove heat.
When HDMI version 1.4 was publicly released in October 2009, it included a number of new features. Most of the new features are barely moving the needle on the consumer electronics industry's Richter scale. But one new HDMI 1.4 feature -- the implementation of 3D video mode -- is about to buckle the pavement of the status quo.
Maxim Integrated Products introduces the MAX31782, a system management microcontroller that combines six temperature measurement channels with six channels of closed-loop fan control. By monitoring multiple temperature points throughout the system...
The Stealth model KYBX-400 series keyboard is an industrial grade keyboard with built-in optical trackball that is environmentally sealed to NEMA 4, 4X, IP65 specifications. This rugged keyboard is housed in a vandal resistant stainless steel enclosure and will stand up to harsh, wet and dirty environments.
The latest in LED lighting offers high luminous flux, efficiency, CRI, and reliability, suitable for most lighting applications, including architectural, accent, HID, and down lighting. LEDs save energy, reduce waste, are free of mercury and lead, and convert energy to light more efficiently than common light sources used today.
The first commercial mobile phone in North America with a built-in camera to capture photographs or video was developed in 2002. As mobile phone usage increases and cameras gain ubiquity in mobile phones, demand for such functionality continues to increase, with significantly strong growth in emerging countries.
For several years now, many of the gadgets we use around the house, on the move and in the workplace have contained some form of visual display to impart status information to the user and even allow the user to interact with them via a touch screen.
The touch screen interface is increasingly becoming a standard requirement in today’s electronic products. But how does one choose the right touch screen for the application? What are the basic considerations when sourcing a touch screen?
Gate drive optocouplers are widely used for driving IGBT and Power MOSFET because of the high output current driving capability. Traditionally, gate drive optocoupler use bipolar transistors for the output stage to deliver high output current.
Are you a “Themimech” engineer? Rising frequencies of many applications are now forcing engineers to be aware of and plan for issues related to rising frequencies in electronic devices and systems and to participate in mutually supportive designs.
For years, radio broadcasters and artists have duked it out over performance rights. Enter the highly-contentious Performance Rights Act, which would expand copyright law to include all public performances of copyrighted sound recordings. And it’s gotten even wilder: an amendment would mandate that all mobile phones contain FM radio chips.
TI introduced a symmetric-polarity transceiver that protects the system from communication losses and potential damage should the signal wires be inadvertently reversed during installation or maintenance.
Spectrum Advanced Specialty Products announces the release of a new L circuit EMI filter designed to provide both inductance and series resistance for superior transient performance.
Power Integrations introduced the SENZero family of ICs that disconnect sense resistors from high-voltage rails during standby or remote-off conditions.
DKN Research recently unveiled a new concept for Ultra Thin Connectors on high-density flexible substrates to showcase the connector’s flexibility and optimize a package design process.
Dave takes you though the basic theory of thermal design and how heatsink calculations work. Then there are some real world temperature measurements to see how close to the theory we get. How do you read a heatsink thermal response graph? What is emissivity? It's all here in thermal design 101.
MPD’s AS212-C automotive socket features weather and vibration resistance in a durable nylon housing. The socket touts easy with the inclusion of a right angle bezel for placement under a panel, dashboard or cabinet. Also included are
Microsemi Corporation today announced the LX5514M power amplifier (PA) in a compact package that matches the industry's smallest 1.5x1.5mm, 0.4mm-high footprint. Microsemi's LX5514M power amplifier supports IEEE 802.11b/g/n WLAN applications in the 2.4-2.5GHz frequency range.
Larson Electronics introduced new high efficiency explosion proof fluorescent lights to complement its expanding line of Class 1 and Class 2 LED lighting for hazardous location areas. Available in two and four foot lengths, the new hazardous location lights use biaxial compact fluorescent bulbs that deliver higher output than traditional T-series tube bulbs.
Zero Defect Software Development (ZDSD) is a results-oriented process that emphasizes the analysis, testing and reporting of the causality of defects. This process, which has evolved from the commitment to providing “five-nines” (99.999%) reliability for mission-critical applications...
Semtech Corp. announced the SC442, a 10-channel white LED driver with an integrated 3A boost power switch. The device is capable of driving up to 120 LEDs at up to 30 mA per channel and is packaged in a low-profile 4 mm x 4 mm x0.6 mm, 28-pin MLPQ package. The SC442 operates
