General Description
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.
Application
The AS7264N applications include:
• Ambient light spectral exposure
• Biological lighting measurements
• Color measurement and absorbance
• Color matching and identification
• Precision color tuning/calibration
