Analog Devices Inc. High-Speed Operational Amplifiers | Featured Product Spotlight

Analog Devices’ LTC6228 high-speed operation amplifiers are fast, low noise, and low-distortion op amps ideal for driving high speed, high dynamic range ADCs. They can also be used in fast photodiode amplifiers or to replace high-speed op amps in existing designs for improved performance. LTC6228 op amps have input-referred voltage noise specified at 0.88nV/√Hz, as well as second and third-order harmonic distortion below — 100dBc with a 2MHz, 4VP-P input.  They’re ideal for applications with a high dynamic range.  They can operate from a single or dual supply configuration with a 2.8V to 11.75V supply range, and the input range of the op amp includes the negative supply rail.  They also have low input offset voltage and drift, as well as a 110dB common-mode rejection ratio. The op amps include input bias cancellation circuitry, and this can be disabled to minimize current noise. The high speed of the LTC6228 allows designers to use it with fast and wide swinging inputs.  It has an 890MHz gain-bandwidth product and a 730MHz -3dB bandwidth. It also has a 500V/µs slew rate. Combined, this lets the LTC6228 drive the output in response to large amplitude, high-frequency inputs. The o...

Master Marine delivers 1,600-hp towboat to St. Louis

Master Marine Inc. (MMI), Bayou La Batre, Ala., recently delivered the towboat Frank Mellor to Osage Marine Services Inc., St. Louis. The new 67’x28′ vessel was designed by Entech Designs LLC, Kenner, La. The towboat is powered by a pair of Laborde Products-supplied Mitsubishi S6R2-Y3MPTAW Tier 3 diesel marine engines rated at 803 hp at 1,400 rpm each. The engines are coupled to Twin Disc 5321 gears. Laborde Products also provided two Northern Lights M65C13.2S 65-kW Tier 3 electronic controlled generators. The towboat is also outfitted with RW Fernstrum keel coolers. A pair of Sound Propeller Services 70″x48″x7″ 4-bladed stainless steel propellers provide thrust through two J&S Machine Works 7″ ABS Grade 2 propeller shafts with all Thordon Bearings, Thorplas bushings and shaft seals. RIO Controls and Hydraulic Inc. supplied the steering system for the two 7″ main and four 7″ flanking rudders. Gulf Coast Air & Hydraulics Inc. provided a pair of Quincy F325 reciprocating air compressors and ventilation fans. Schuyler Maritime LLC furnished all 18″x12″ rubber fendering around the entire perimeter of the vessel and push knees. Outfitters International provided a Daiken mini-...

The initial justification for developing these lasers was to bring the benefits of fiber lasers to

The initial justification for developing these lasers was to bring the benefits of fiber lasers to low-average-power, low-duty-cycle pulsed laser welds. Cladding pumped fiber lasers have been a major success in the laser industry in the last decade and recent reports suggest this trend is set to continue. Both low-power fiber lasers for marking and high-power multi-kilowatt fiber lasers for cutting and welding are rapidly growing their market share. Recent reports suggest that the number of multi-kilowatt fiber lasers employed in industry for flat sheet metal cutting will very soon overtake the number of CO2 lasers sold into the largest industrial laser market [1]. In addition, fiber laser components in the form of fiber amplifiers or fiber oscillators are now being widely adopted as key components for building shorter pulse lasers in the picosecond and femtosecond regime. Here, we report on a third type of fiber laser that is also making rapid progress in capturing market share. A range of infrared (IR) fiber lasers known as quasi-continuous-wave (QCW) lasers are now rapidly displacing the long-established Nd:YAG flashlamp pumped laser technology. The generic benefits of fiber ...

How To Determine How Many LED Lumens You’ll Need To Properly Light Your Space

What is enough light? The question is difficult enough but when faced with having to calculate how much LED lighting you need to create a well-lit space, it can become a bit more complicated. Whether it’s architectural LED lighting for commercial applications or residential applications, here’s how to determine how many LED Lumens you’ll need to properly light your space. A measurement of light emitted by a source, whether it’s LED, Fluorescent, Halogen, or Incandescent. This is also known as “brightness” or “light output.” Your reference point: A standard 100-watt incandescent light bulb produces about 1,500 – 1,700 lumens. Not a measure of brightness; instead, it’s a measure of how much electricity (or energy) a bulb consumes to reach its claimed brightness. Each type of light source, LED, Fluorescent, Halogen, or Incandescent has a different lumen-per-watt ratio. Below we’re going to use lumens as a measurement to make sure we have enough light for a space. Since we’ve conflated watts and lumens, it’s easier to talk about bulbs in terms of watts. So if a 100-watt incandescent produces 1,500 lumens, and a 10-watt LED does the same, the 10-Watt LED may advertise “100-watt equiv...

Sudan Shriners doing their part to help – News – Gaston Gazette

Sudan Shriners has been a cornerstone of the New Bern community since the early 1900s, with its current headquarters based on Broad Street since the 1950s. They are most often seen during their extravaganza parades, a marching circus with clowns, street performers, musicians and drivers – characters riding most anything with wheels, from mini trucks and cars to coolers. Shriners are also known as Nobles. Behind the fun and festivities, there is a very noble cause – free medical care for crippled and burned children through 22 pediatric specialty hospitals in North America. During the past quarter-century, while Sudan Roadrunners were busy transporting children to the hospitals, the Eastern North Carolina Shrine clubs and units raised nearly $10 million with fish fries, barbeque dinners, golf tournaments and other activities to support the Shriners Hospitals for Children. Nobody knows the glitzy side and the work side of Shiners better than Sudan’s new Potentate, Allen “Buddy” Brown of Dunn. He’s been a parade clown for 20 years. “I feel like people have a desire to help their fellow man,” he said. “I always have. I was raised that way. What brought me to Shriners was a fri...
