[v1-03] 2018-Dec-19 Document Feedback TCS3707 ALS/Color Sensor with Flicker Detection The TCS3707 features ambient light and color (RGB) sensing, proximity and flicker detect ion. The device comes in a low-profile and small footpr int, L2.5mm x W2.0mm x H0.5mm package. The Ambient Light and Color Sensing function provides five concurrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband. The RGB an d 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 device integrates direct detection of 50Hz or 60Hz ambient light flicker. Flicker detection is executed in parallel with ambient light and color sensin g and has independent gain configuration. The flicker detection engine can also buffer data for calculating other flicker frequencies externally. General Description
