Description
The ALS-PDIC17-57B/TR8 is a digital-output light sensor with a two-wire, I²C serial interface that is compatible
with SMBus operating at 100 KHz serial clock frequency. It combines a photodiode and an analog-to-digital converter
(ADC) on a single CMOS integrated circuit to provide light measurements over an effective 15-bit dynamic range.
Provided with constantly refreshing ADC. The integrating conversion technique used by ALS-PDIC17-57B/TR8
effectively eliminates the effect of flicker from AC-powered lamps, increasing the stability of the measurement.
ALS-PDIC17-57B/TR8 is very close to human-eye vision, having very low response to non-visible light, such as
infrared and ultra-violet light.
Applications
‧Detection of ambient light to control display backlighting
Mobile devices – Mobile phones, PDAs, Table PC and GPS
Computing device – TFT LCD monitor
Consumer device – TFT LCD TV, Plasma TV, Video camera, Digital camera, Toys
‧Detection of ambient light for controlling the backlighting of TFT LCD display
‧Automatic residential and commercial lighting management
‧Automatic contrast enhancement for electronic signboard
‧Ambient light monitoring device for daylight and artificial light
