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 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 register set, or with a high level AT Spectral Command set via a serial UART.
