VD6283TX Hybrid Filter Multispectral Sensor


STMicroelectronics’ VD6283 (1.83 mm x 1.0 mm x 0.55 mm) is a color sensor with advanced light flicker extraction. Light measurement is fast and accurate thanks to an individual ADC and a readout for each color channel. The VD6283 uses hybrid color filters with precise responses allowing accurate computation of the correlated color temperature (CCT) and Lux information. The VD6283 can be used for display brightness management or scene light correction.

With a patented architecture and a high-performance photodiode design, the VD6283 can extract light flickering frequencies to avoid banding effects on videos or check that they are safe for the human eye. Additionally, the VD6283 is the only sensor able to extract different light flicker waveforms from 100 Hz and 2 kHz, including LED square signals, that can run flicker operations simultaneously with ALS operations.
