With its new, miniature light sensor AMS402Y, Panasonic Electric Works expanded its NaPiCa series at the beginning of 2008.
With dimensions of only 1.25 x 2.00 x 0.55mm (LxWxH), this "chip type" light sensor includes all the advantages of its predecessors and lends itself to any number of applications.
Despite its miniature size, like the other NaPiCa light sensors the AMS4 only processes that part of the spectrum detected by the human eye and, thanks to its integrated amplifier, produces an output current that is linearly proportional to the illumination.
Improved energy efficiency and reduced reaction times predestine the AMS4 to be used in brightness detection applications in displays for mobile devices, from mobile phones and PDAs to digital cameras.
Using energy efficiently these days is not only of paramount importance for mobile applications, but also for monitors and display elements, whose size 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 struck a positive note with users.
In the future, this kind of light sensing technology, which complies 100% with the RoHS guidelines, will replace aging LDRs (light dependent resistors).
Due to their substantial technical advantages and their attractive price, the NaPiCa series--including the new AMS4--can look forward to enjoying a bright future.
