The proximity function synchronizes IR emission and detection to sense nearby objects. This architecture accurately measures ambient light and enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance. The RGB and Clear channels have a UV/IR blocking filter. The Ambient light and color sensing function provide five rrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband. The TCS3707 is a very-high sensitivity light-to-digital converter that features ambient light and color (RGB) sensing, proximity and flicker detection. The proximity engine recognizes detect/release events and produces a configurable interrupt whenever the proximity result crosses upper or lower threshold settings. Sensitivity, power consumption, and noise can be optimized with adjustable IR LED timing and power. The architecture of the engine features self-maximizing dynamic range, ambient light subtraction, advanced optical crosstalk noise cancellation, 14-bit data output and interrupt-driven 1.8V I☬ communications interface. The IR driver needs to be connected to an external LED or VCSEL emitter.
The Ambient light and color sensing function provides five concurrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband.
The TCS3701 is a very-high sensitivity light-to-digital converter that features ambient light and color (RGB) sensing in parallel with IR proximity detection.
