AS73211 XYZ True Color Sensor with IC Interface

The AS73211 is a low-power, low-noise integrated color sensor designed for accurate light measurement. It features three channels with photodiodes and optical filters for X-, Y-, and Z-signal conversion, enabling continuous or triggered measurements. The sensor offers adjustable irradiance responsivity and conversion time, providing a wide dynamic range of up to 3.43E+10 and up to 24-bit signal resolution. Its inherent ripple rejection for 50Hz/60Hz disturbances, automatic power-down, and standby modes make it suitable for mobile applications. The AS73211 supports various operating modes including CMD, CONT, and SYNS/SYND for flexible measurement control. It is ideal for photometry, LED lighting control, ambient light color detection, display calibration, and mobile light measurement applications. An integrated temperature sensor aids in rough compensation of light source thermal behavior.
