General Description
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 enables additional application flexibility. LED drivers with programmable currents are provided 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.
