ams AS7263 6-Ch NIR Spectral Sensing Engine

The AS7261 integrates Gaussian interference filter technology to enable chromatic white color sensor which provides direct XYZ color coordinates consistent with the CIE 1931 2° standard observer color coordinates. Additional mapping of XYZ coordinates to the x, y (Y) of the 2-dimensional color gamut and scales of the CIE 1976 u’v’ coordinate system, providing accurate correlated color temperature (CCT) measurements and color point deviation from the black body curve for white light color in the ∆u’v’ coordinate system. A near-IR channel and LED drivers with programmable currents increase application flexibility, including support for electronic shutter applications. Control and spectral data access is implemented either through either the I²C virtual register set, or via the serial UART enabling use of the high level smart spectral command set.

The AS7262 is a cost-effective multispectral sensor-on-chip solution designed to address spectral ID applications. This highly integrated device delivers 6-channel multispectral sensing in the visible wavelengths from approximately 430nm to 670nm with full-width half-max (FWHM) of 40nm. An integrated LED driver with programmable current is provided for electronic shutter applications. The AS7262 integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology and is packaged in a 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.
