AS7264N Spectral Sensor

XYZ Chromatic Color and 440/490nm Blue Sensor with Electronic Shutter


The AS7264N provides direct XYZ sensor data which conforms to the tri-stimulus standard observer color response of the human eye. In addition, two channels added for measurement of blue spectrum light, plus a near-IR channel enables additional application flexibility. LED drivers with programmable currents are provided for electronic shutter applications.

The AS7264N integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology and is packaged in an LGA package that provides a built in aperture to control the light entering the sensor array.

Control and spectral data access is implemented through an I²C register set
