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
