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.
