Features, Applications
6-Channel NIR Spectral_ID Device with Electronic Shutter and Smart Interface

The is a digital 6-channel spectrometer for spectral identification in the near IR (NIR) light wavelengths. AS7263 consists of 6 independent optical filters whose spectral response is defined in the NIR wavelengths from approximately to 870nm with full-width half-max (FWHM) 20nm. An integrated LED driver with programmable current is provided for electronic shutter applications. The AS7263 integrates Gaussian filters into standard CMOS silicon via Nano-optic deposited interference filter technology and is packaged 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.
