Description

The ALS-PDIC144-6C/L378 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.

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

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 ≦Vout(saturation)＝Vcc－1.2V 6 Copyright Revision :2 © LifecyclePhase: Release Date:2012-10-26 17:35:57.
