Avago Technologies Introduces Low-Cost Ambient Light Photo Sensor for Controlling Backlighting in Consumer Applications.Automatic Adjustment Feature Extends Screen and Battery Life in Portable LCD Display Products SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Avago Technologies Avago Technologies is an American company which was earlier the semiconductor products division of HP and later Agilent Technologies, before being spun off into a distinct legal entity. It holds more than 2,000 patents. , the world's largest privately held semiconductor company, today introduced a new version of its analog-output ambient light photo sensor that helps to conserve power and extend the life of LCD screens in portable display devices. These low-cost sensors control the backlighting back·light n.

Avago's APDS-9004 is an ideal power-savings solution for notebook PCs, portable DVD players A handheld device with a built-in DVD drive and flip-over lid that contains a screen, typically 6" to 10" in size. It may support rear seat passenger viewing, in which case the unit is hung upside down from the back of the front seat head rest, and a switch flips screen content 180 , camcorders, digital cameras, and mobile phones. It can also be used for turning on/off indoor and outdoor lighting, street lighting and electronic signs and signals. The APDS-9004 sensor detects the ambient light level and provides a highly linear proportional output that is used to adjust the backlighting of a display screen or keypad. If there is sufficient ambient light, designer-provided logic can turn off the backlighting to reduce battery recharges or replacements. Avago's low-cost reverse-mount photo sensor offers additional flexibility to designers of price- and size-sensitive mobile products. The ultra-small APDS-9004 sensor offers a combination of excellent performance with significant power savings, which is an increasingly important issue with today's battery-powered products. Avago's ambient light sensors out perform silicon photodiode A light sensor (photodetector) that allows current to flow in one direction from one side to the other when it absorbs photons (light). The more light, the more the current. Used to detect light pulses in optical fibers and other light-sensitive applications, it works the opposite of a light-detection solutions because their spectral response The variable output of a light-sensitive device that is based on the color of the light it perceives. peaks at the same wavelength as the human eye. The sensors perform equally well with light sources ranging from natural sunlight to fluorescent, conventional incandescent, and halogen lamps. They also offer significantly faster response to changes in illumination than phototransistors. Avago's package, developed for surface-mount LEDs, combines low cost, proven reliability and optimization for automated manufacturing processes with an extremely small, industry-standard footprint. Features The APDS-9004 sensor is supplied in a reverse-mount four-pin package with Electronic Industries Association (EIA (Electronic Industries Alliance, Arlington, VA, www.eia.org) A membership organization founded in 1924 as the Radio Manufacturing Association. It sets standards for consumer products and electronic components. ) standard dimensions of 3.2 mm by 1.6 mm by 1.1 mm. It mounts with the light sensitive area facing toward the PC board with light passing through a user-provided aperture. This allows the board to be mounted tightly against the case of the product resulting in space savings. Performance of the APDS-9004 ranges from 2.4 V to 5.5 V and -40 C to +85 C in temperature. U.S. Pricing and Availability The APDS-9004 is priced at less than $0.50 each in moderate volumes. It is available now through Avago's direct sales channel and worldwide distribution partners.
