Product Description
ams OSRAM AS7264N XYZ Chromatic Color and 440/490nm Blue Sensor with Electronic Shutter
The AS7264N is a digital color sensor that provides direct XYZ tri-stimulus data conforming to the human eye's color response. It features two additional channels for measuring blue spectrum light at 440nm and 490nm, along with a near-IR channel for enhanced application flexibility. Integrated Gaussian filters and a built-in aperture in the LGA package ensure accurate ambient light measurements. The device includes programmable LED drivers for electronic shutter applications and is controlled via an IC interface.
