General Description

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.

RECOMMENDED NEWER DESIGN: AS7341

This product suits for the following applications:

  • Spectral Color Matching and monitoring
  • Detection of color mixture effects (e.g. textiles, paints, etc.)
  • Authentication and counterfeit detection
  • Fluid monitoring and analysis (using reagents)
  • ID marker detection
