ams AS7261N - Spectral Sensor

Not for new design
Not for new design


The AS7261N provides direct XYZ sensor data which conforms to the tri-stimulus standard observer color response of the human eye. A near-IR channel and LED drivers with programmable currents increase application flexibility, including support for electronic shutter applications.The AS7261N 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 an I²C register set.



  • Tri-stimulus XYZ+NIR realized by silicon interference filters
  • Integrated programmable LED drivers
  • I²C slave digital interface with optional interrupt operation
  • 16-bit ADC with digital access
  • 20-pin LGA package 4.5mm x 4.7mm x 2.5mm, with built-in aperture


  • Stable filter conditions over temperature and life time
  • Compact true-color sensing, XYZ coordinates direct from the sensor
  • Direct register read and write with interrupt on sensor ready
  • Signal conditioning on chip
  • Sample illumination without external LED driver
