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.
