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
