5mm T-1 3/4 Ambient Light Sensor

ALS-PT243-3C/L177
‧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 ‧Operation temperature performance, -40oC to 85oC ‧Wide supply voltage range, 2.5V to 5.5V ‧Size 5mm Lamp Flat lens ‧RoHS compliant and Pb Free package

The ALS-PT243-3C/L177 is an ambient light sensor, consisting of phototransistor 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.
‧Detection of ambient light to control display backlighting
