![]() The AS7343 is a 14-channel highly versatile, multi-purpose spectral sensor enabling new consumer, commercial, industrial and laboratory applications. The device is available in an ultra-low profile package with dimensions of 3.1mm x 2mm x 1mm. Control and Spectral data access is implemented through a serial I☬ interface. AS7341 integrates filters into standard CMOS silicon via Nano-optic deposited interference filtertechnology and its package provides a built in aperture to control the light entering the sensor array. The device can also be synchronized to external signals via pin GPIO. The NIR channel in combination with the other VIS channel may provide information of surrounding ambient light conditions (light source detection). The flicker detection engine can also buffer data for calculating other flicker frequencies externally. The device also integrates a dedicated channel to detect 50Hz or 60Hz ambient light flicker. ![]() 8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photo diode without filter (“clear”). 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. AS7341 is an 11-channel multi-spectral sensor for color detection and spectral analysis applications.
