ALS-PDIC17-79NB-TR8 Overview
The ALS-PDIC17-79NB/TR8 is a digital-output light sensor with a two-wire, I2C serial interface that is patible with SMBus when working at 100kHz serial clock frequency. It bines 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...
