AS7263 Spectral Sensing Engine

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


The AS7263 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 600nm to 870nm with full-width half-max (FWHM) of 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 I²C register set, or with a high level AT Spectral Command set via a serial UART.

Key Features

  • 6 near-IR channels realized by silicon interference filters: 610nm, 680nm, 730nm, 760nm, 810nm and 860nm, each with 20nm FWHM
  • UART or I²C slave digital Interface
  • 16-bit ADC with digital access 

Key Benefits

  • Compact spectrometry solution
  • Simple text-based command interface via UART, or direct I²C register read and write
  • Lifetime-calibrated sensing with no drift over time or temperature
  • Small, robust package, with built-in aperture
