3 Description

The OPT4060 is a single-chip high resolution color sensor, capable of measuring four channels each with specific engineered spectral responses. Three of the four channels have peak spectral responses in the red, green and blue wavelengths with the fourth channel having a wide band spectral response. With measurements from these channels, important characteristics of the lighting environment can be extracted like (i) light intensity (lux) and (ii) color. The OPT4060 is available in a small SOT-5X3 package.

The OPT4060 has a selectable addressing scheme to enable up to four devices on a shared I2C bus. The spectral response of the channels have been specially tuned for color detection, with strong rejection for wavelengths away from their respective peaks, especially the NIR (850 nm and 940 nm) region. The filters use an advanced filter technology which provides excellent filter performance even at higher angles of light incidence.
