Offering six software-programmable output ranges, the LTC2755-16 quad 16-bit current output digital-to-analog converter (DAC) from Linear Technology provides 16-bit linearity (±1LSB (max) INL and DNL) over the industrial temperature range without any adjustment. Each DAC output can be individually programmed through a parallel interface or can be pin-strapped for operation within a single range.
Samtec expanded its Board-to-Board and Cable-to-Board line featuring a rugged Edge Rate contact. These systems are designed for applications where signal integrity and durability are critical. The specially designed contacts are asserted to offer impedance matching, reduced broadside coupling and crosstalk, and high cycle life. Board level systems include the
Designed to meet indoor and outdoor LED screen requirements for better screen resolution (greater than 12 mm pixel size), Avago’s ASMT-YTB0 LEDs have six leads to enable individual color control of each chip. Features of the PLCC-6-packaged silicone-encapsulated devices include a 115° viewing angle , an MSL 2a moisture sensitivity level
The RGB MicroSIDE LED from OSRAM Opto Semiconductors features an ultra-slim design and delivers high brightness for in-coupling into light guides designed for backlighting in space-sensitive applications. Featuring three individual color chips, the device is presented as having the highest
Endicott Research Group (ERG) has released two Smart Force solid state lighting driver (SSLD) boards as standard products for industrial and medical LCDs. The SFDE (Economical) and SFDM (Mini) Series provide full function power supplies for high brightness as well as low power consumption, low cost and a compact size.
Designed to enable the reduction in overall motor sizes, Avago’s AEDT-9340 encoder module targets Brushless DC motors used in industrial and factory automation equipment. The device includes a lensed LED source and a detector IC enclosd in a small plastic package with a switching accuracy of ±1°
It may have been a cold and damp morning in Manhattan, but that didn’t damp the passions of the participants in the Challenge X national collegiate engineering competition. This year’s challenge, sponsored by the US Department of Energy and General Motors, focuses on technology integration and full-vehicle development of advanced alternate-technology drivetrain and subsystems. By participating in the Challenge X program, the students gain real-world engineering skills and hands-on learning to better prepare them for a future career in engineering.
A variety of tools simplifies the trip from abstract DSP models to real signal-processing hardware.
Driving the next generation of handheld devices, the TPS65136 solid-state lighting driver (SSLD) from Texas Instruments manages power to AMOLED (active-matrix organic light-emitting diode) displays up to 2.5" with a buck-boost topology that allows the device to generate a positive voltage up to 4.6 V and adjustable negative output voltage down to -7 V.
In full compliance with power specifications released in draft 3.0 of the IEEE802.3at, a family of power-over-ethernet (PoE) midspan power injectors from Phihong can provide up to 33.6 W per port. Available in single-, 4-, 8- and 16-port models, the devices support demanding peripherals such as new IEEE802.11N broadband access points.
For line of sight near-field bidirectional wireless communication applications would you rather use IrDA light-based methodologies or RF?
Created to measure the electromagnetic fields of extremely low frequency (30 to 300Hz) devices such as electric transmission equipment, microwave ovens, air conditioners, computer monitors, and video/audio devices, the HHG191 Gauss meter from Omega Engineering represents allows measurements up to 2,000 mG to 200 micro-tesla with a basic accuracy of 2.5% + 6-digit.
