RGB Color Sensor

1. Description
CPS289AL is a light to voltage converting sensor and combines a photodiode array and threetransimpedance amplifiers in a single monolithic IC. With a Red (R), Green (G) and Blue (B)color filters coated over the photodiode array, the sensor converts RGB light to analog voltage
outputs, denoted by VROUT, VGOUT and VBOUT, respectively. Also an IR cut-off filter on thechip blocks the transmission of the infrared while passing the visible. The sensor packaged in a
3.5x3.0x0.7 [mm] surface mount COB-12 package is ideal for various small optical units.
