Agilent Technologies Inc. recently announced a new version of its
analog-output ambient light photo sensor for consumer, mobile, industrial
and commercial products. The Agilent APDS-9002 sensor is supplied in the
miniature ChipLED lead-free surface-mount package, which features one of the
smallest dimensions in the industry at 2.00 mm x 1.25 mm x 0.80 mm. Its compact
package reduces board space, making it possible to design even slimmer,
feature-rich products.
Agilent's ambient light photo sensors are an ideal power-savings solution for
PDAs, notebook PCs, MP3 players, portable DVD players, camcorders and digital
cameras, as well as mobile phones. They may also be used for turning on/off
indoor and outdoor/street lighting and electronic signs/signals.
"Our new ChipLED photo sensor addresses a range of applications,
including price- and size-sensitive mobile phones," said Chee-Kien Lim,
worldwide marketing manager for the Infrared Products Division in Agilent's
Semiconductor Products Group. "The ultra-small sensor offers improved
performance and significant power savings, which is an increasingly important
issue with today's battery-powered products."
Compared with Agilent's HSDL-9001 light sensor, the APDS-9002 offers improved
performance, including 2.4 V to 5.5 V supply voltage range, and the wider -40 C
to +85 C temperature range. Agilent's innovative ambient light photo sensors
emulate the human eye in detecting the amount of ambient light, then signaling
the mobile phone to turn on its display's backlight and keypad light if
necessary.
The new 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.
Agilent's ambient light sensors outperform silicon photodiode light-detection
solutions because their spectral response 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. The ChipLED package, developed for surface-mount LEDs,
combines low cost, proven reliability and optimization for automated
manufacturing processes with an extremely small, industry-standard footprint.
U.S. Pricing and Availability
The APDS-9002 is available now through Agilent's direct sales channel and
worldwide distribution partners. It is priced at less than $0.50 each in
moderate volumes. More information is available at www.agilent.com/view/ir.
