NOA1302

NOA1302 Ambient Light Sensor with I2C Interface Description The NOA1302 integrates a wide dynamic range ambient light sensor (ALS) with a 16−bit ADC and a 2−wire I2C digital interface. The NOA1302 ambient light sensor provides a linear response over the range of close to 0 lux to well over 100,000 lux with programmable integration times to optimize noise performance. The sensor employs proprietary CMOS image sensing technology from ON Semiconductor which provides low noise and high dynamic range output signals and light response similar to the response of the human eye. The NOA1302 operates as an I2C slave device and supports commands to set options in the device and read out the ambient light intensity count. Features Senses Ambient Light and Provides an Output Count Proportional to the Ambient Light Intensity Human Eye Type of Spectral Response Provides Comfortable Levels of Display Depending on the Viewing Environment Linear Response Over the Full Operating Range Senses Intensity of Ambient Light from ~0 Lux to over 100,000 Lux Programmable Integration Times of 400 ms, 200 ms and 100 ms No External Components Required Low Power Consumption Built−in 16−bit ADC I2C Serial Communication Port − Standard Mode – 100 kHz − Fast Mode – 400 kHz This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant Applications Saves Display Power in Applications such as: − Laptops, Notebooks, Digital Signage − LCD TVs and Monitors, Digital Picture Frames − LED I...
