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. Two operation modes are provided with one for constantly refreshing ADC and the other for one time integration. When working in “one time integration” mode, no external resister is required. The integrating conversion technique used by ALS-PDIC17-79NB/TR8 effectively eliminates the effect of flicker from AC-powered lamps, increasing the stability of the measurement. ALS-PDIC17-79NB/TR8 wavelength is close to human-eye, and low response to non-visible light, such as infrared and ultra-violet light. Applications • 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 Revi1sion Copy:rig3ht © 2010, Everlight All Rights Reserved.
