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

Converting Photocurrent to Voltage
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,
