AS7261 Demo Kit ams

AS7264N XYZ Chromatic Color and 440/490nm Blue Sensor with Electronic Shutter The AS7264N provides direct XYZ sensor data which conforms General Description to the tri-stimulus standard observer color response of the human eye. In addition, two channels added for measurement of blue spectrum light, plus a near-IR channel enables additional application flexibility. LED drivers with programmable currents are provided for electronic shutter applications. The AS7264N 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 IC register set. Ordering Information and Content Guide appear at end of datasheet.
