Description
AI
The VD6283TX (1.83 x 1.0 x 0.55 mm) is the third version of ST's ambient light sensors with advanced light flicker extraction. Light measurement is fast and accurate thanks to an individual ADC and a readout for each color channel. The VD6283TX uses hybrid color filters with precise responses which enhance the accuracy of the correlated color temperature (CCT) and Lux performance. The VD6283TX can be used to assist camera white-balance in less than 30 ms.
With a patented architecture and a high-performance photodiode design, the VD6283TX can extract light flickering frequencies to enhance camera experience, and avoid "banding effects" on videos or viewfinder modes. Additionally, the VD6283TX is the only sensor able to extract different light flicker waveforms, including LED square signals that can run flicker operations simultaneously with ALS operations.
