ams OSRAM AS7264N Ambient Light Sensor

ams OSRAM AS7264N Ambient Light Sensor provides direct XYZ sensor data, which conforms to the human eye's tri-stimulus standard observer color response. This AS7264N XYZ sensor integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology and is packaged in an LGA package. 

The AS7264N sensor is a next-generation digital color sensor device. This AS7264N sensor senses X, Y, and Z standard observer filters compliant with the CIE 1931 standard observer color response. The AS7264N sensor spectral conversion is implemented via two photodiode banks. Features include two added blue channels at 440nm and 490nm, 16-bit ADC with digital access, and an I2C slave digital interface. Typical applications are ambient light spectral exposure, biological lighting measurements, color matching and identification, and color measurement and absorbance.
