AS7261

XYZ Chromatic White Color Sensor +

NIR with Electronic Shutter and Smart

Interface

The AS7261is a chromatic white color sensor providing direct

XYZ color coordinates consistent with the CIE 1931 2° Standard

Observer color coordinates. It also maps the XYZ coordinates

to the x, y (Y) of the 2-dimensional color gamut and scales the

coordinates to the CIE 1976 u’v’ coordinate system.

The device provides accurate Correlated Color Temperature

(CCT) measurements and provides color point deviation from

the black body curve for white light color in the delta u’ v’

coordinate system. It also integrates a Near-IR channel for other

applications. LED drivers with programmable currents are

provided for electronic shutter applications.

The AS7261 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 either

the I²C register set, or with a high level AT Spectral Command

set via a serial UART.

Ordering Information and Content Guide appear at end of

datasheet.
