Description
The EAALST03RDAA0 is an ambient light sensor; It consists of a phototransistor in 3mm lamp. Everlight Americas
ALS series products are 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, 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

Note :
1. The output voltage (Vout) is the product of photocurrent (IPH) and loading resistor (RL)
2. A right loading resistor shall be chosen to meet the requirement of maximum ambient light,
and output saturation voltage:
Vout(max.) = Iout(max.) × RL
