AS7264N

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

Ordering Information and Content Guide appear at end of

datasheet.
