ALS-PDIC17-57B-TR8

Surface - Mount I2C Digital Ambient Light Sensor ALS-PDIC17-57B/TR8 Features ‧Close to the human eye's response ‧15 bit effective resolution ‧50Hz/60Hz rejection ‧Low sensitivity variation across various light sources ‧Operating temperature performance, -40oC to 85oC ‧Wide supply voltage range, 2.7V to 5.5V Low power consumption, less than 2mW while operating Shut-down mode, current consumption less than 0.1uA 2 I C serial port communication: (1) Standard 100kHz, (2) Fast 400kHz ‧High dynamic sensing range and from 0 to 88,000 Lux ‧Dimension: 2.0mm(L)x2.0mm(W)x0.6mm(H) ‧RoHS compliant and Pb Free 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. One operation modes are provided with constantly refreshing ADC. When working in “one time integration” mode, no external resister is required. 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 backlight...
