The SIP5009 is a 14-channel spectral sensor for spectral identification, passive ambient light measurement, and color calibration. Its spectral response is defined by individual channels, covering a range from approximately 380 nm to 1000 nm. Eight channels are centered in the visible spectrum (VIS) region, plus one near-infrared (NIR) channel and one transparent channel. The NIR channel, combined with the other VIS channels, provides information on ambient light conditions, including light source detection. Light source detection is aided by an integrated flicker detection channel, which buffers data for external calculation of other flicker frequencies up to 3 kHz.

The SIP5009 integrates a high-precision optical filter onto a standard CMOS silicon wafer. Device control and spectral data access are achieved via a serial I2C interface. The device is housed in a small package measuring 3.1 mm × 2 mm × 1 mm.
