ams TCS3408 Color Sensor

The TCS3707 is a very-high sensitivity light-to-digital converter that features ambient light and color (RGB) sensing, proximity and flicker detection. The Ambient light and color sensing function provide five rrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband. The RGB and Clear channels have a UV/IR blocking filter. This architecture accurately measures ambient light and enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance. The proximity function synchronizes IR emission and detection to sense nearby objects. The IR driver needs to be connected to an external LED or VCSEL emitter. The architecture of the engine features self-maximizing dynamic range, ambient light subtraction, advanced optical crosstalk noise cancellation, data output and interrupt-driven 1.8V I²C communications interface. Sensitivity, power consumption, and noise can be optimized with adjustable IR LED timing and power. The device integrates direct detection of 50Hz or 60Hz ambient light flicker. Flicker detection is executed in parallel with ambient light and color sensing and has independent gain configuration. The flicker detection engine can also buffer data for calculating other flicker frequencies externally.
