EAALST05RDMA0

Ambient Light Sensor – DIP 5mm T-1 3/4 EAALST05RDMA0 Features • Close responsively to the human eye spectrum • Light to Current, analog output • Good output linearity across wide illumination range • Low sensitivity variation across various light sources o o • Guaranteed temperature performance, -40 C to 85 C • Wide supply voltage range, 2.5V to 5.5V • Size : 5mm Lamp (Flat lens) • RoHS compliant and Pb Free package • Compliance with EU REACH. Description The EAALST05RDMA0 is a low cost ambient light sensor, consisting of phototransistor in miniature SMD. Everlight Americas ALS series product are a good effective solution to the power saving of display backlighting of mobile appliances, such as the mobile phones, NB and PDAs. Due to the high rejection ratio of infrared radiation, the spectral response of the ambient light sensor is close to human eyes. Applications • Detection of ambient light to control display backlighting • Mobile devices – mobile phones, PDAs Computing device – TFT LCD monitor for Notebook computer Consumer device – TFT LCD TV, plasma TV, video camera, digital camera, toys • Automatic residential and commercial management • Automatic contrast enhancement for electronic signboard • Ambient light monitoring device for daylight and artificial light – Street light, CCD/CCTV 1 Copyright © 2010, Everlight Americas Inc.
