AS7262-BLGT

AS7262 6-Channel Visible Spectral ID Device with Electronic Shutter and Smart Interface The AS7262 is a cost-effective multi-spectral sensor-on-chip General Description solution designed to address spectral ID applications. This highly integrated device delivers 6-channel multi-spectral 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 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 IC 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.
