Recently, Panasonic Electric Works expanded its NaPiCa light sensor range with its new, miniature SMD device, AMS402Y.
Measuring just 1.25 x 2.00 x 0.55mm (LxWxH), this tiny "chip type" light sensor includes all the benefits and features of its predecessors. It can be applied in a wide range of applications.
It may be miniature in size, but, as with all other NaPiCa light sensors, the AMS4 processes only that part of the light spectrum detected by the human eye and, as a feature of its integrated amplifier, produces an output current that is linearly proportional to the illumination.
With improved energy efficiency and reduced reaction times the AMS4 is highly suitable for use in brightness detection applications in displays for mobile devices ranging from mobile phones and PDAs to digital cameras.
In the current economic and business environment using energy efficiently is not only of paramount importance for mobile applications, but also for monitors and displays, the size of which continues to increase. Plasma TV and LCD monitors already adjust their brightness based on ambient light by using light sensors. The resulting improved ergonomic display and visibility have been widely welcomed by users.
In future applications, NaPiCa light sensing technology, which complies 100% with the RoHS guidelines, will increasingly replace aging LDRs (light dependent resistors).
Offering substantial technical advantages and an attractive price, the NaPiCa series--including the new AMS4--can look forward to offering users a bright future.
