AS7263 NIR 6-Channel Spectral ID Device with Electronic Shutter & 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 approximately600nm 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
  • Programmable LED drivers
  • 20-pin LGA package 4.5mm x 4.7mm x 2.5mm

Key Benefits

  • Compact 6-channel spectrometry solution
  • Simple text-based command interface via UART, or direct register read and write with interrupt-on-sensor-ready option on I2C
  • Lifetime-calibrated sensing with no drift over time or temperature
  • No additional signal conditioning required
  • Small, robust package, with built-in aperture

Applications

  • Product Authentication
  • Bank Note/Document Validation
  • Chemical analysis
  • Authentication and brand protection
  • Food/beverage safety
