ams TCS3410 Color and Flicker Detection Sensor



The TCS3410 features ambient light sensing, as well as flicker detection. The device comes in a low-profile and small footprint, L2.0mm x W1.0mm x H0.5mm optical QFN package. The Ambient Light Sensing function provides three concurrent ambient light and flicker sensing channels, which can be arbitrarily connected to the photodiodes via a programmable multiplexer. TCS3410 incorporates a set of RGB photodiodes and a Clear photodiode. The RGB and Clear photodiode area is covered with a UV/IR blocking filter. This architecture accurately measures ambient light and enables the calculation of irradiance of different light sources. Calculation results help to improve display appearance and picture taking. The device also integrates direct detection of ambient light flicker. Flicker detection is executed in parallel with ambient light sensing and has independent gain configuration. The flicker detection engine will sample and buffer data for calculating flicker frequencies externally on a host CPU.
