TCS3400 Light-to-Digital Converters ams OSRAM TCS3400 Light-to-Digital Converters provide Red, Green, Blue, and Clear-light-sensing (RGBC) that detects light intensity under a variety of lighting conditions and attenuation materials. These converters are useful in lighting conditions containing minimal IR content like LED RGB backlight control, reflected LED color sampler, or fluorescent light color temperature detector. The TCS3400 converters act as an excellent ambient light sensor, color temperature monitor, and general-purpose color sensor by adding an IR blocking filter. Typical applications include color temperature sensing, color display closed-loop feedback control, industrial process control, and medical diagnostics.
