Ambient Light Sensor 5mm T-1 3/4 ALS-PDIC243-3B Features ‧Excellent IR-Cut performance ‧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 ‧Operation temperature performance, -40 C to 85 C ‧Wide supply voltage range, 1.8V to 5.5V ‧Size: 5mm Lamp (Flat lens) ‧RoHS compliant package Description The ALS-PDIC243-3B is an ambient light sensor, which incorporates a photodiode and a current amplifier IC in DIP package. EVERLIGHT ALS series products 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. Also, it is very suitable to use ALS product for opto-switch application. Applications ‧Ambient light monitoring device for daylight and artificial light – CCD camera/CCTV security equipment, Street light ‧Detection of ambient light to control display backlighting Computing device – TFT LCD monitor for Notebook computer Consumer device – TFT LCD TV, video camera, digital camera, toys 1 Copyright Revision :4 © LifecyclePhase: 2012, Everlight All Rights Reserved.
