CM3320 Color Sensor (RGB Sensor, RGBS) is a highly integrated design for RGB light sensing surface mount solution. In a single chip, it incorporates the photodiode for Red/Green/Blue light inpidually sensing amplifiers, analog / digital circuits and I2C protocol interface by analog CMOS process.

CM3320’s adoption of the Filtron™ technology allows the closest ambient light spectral sensitivity to real human eye responses. Capella RGBS has an excellent temperature compensation capability via an embedded temperature sensor for keeping the output stable under various temperature configurations, and provides temperature information for the system application usage. Its robust refresh rate setting does not need an external RC low pass filter. CM3320 operation voltage ranges from 2.7V and 5.5V.
