CM3605 is a highly integrated design for a distance detection and ambient light sensing solution. It incorporates a photodiode, amplifiers, and analog/digital circuits into a single chip by the CMOS process. CM3605 offers outstanding optical precision by O-TrimÔ packaged-level trim. O-Trim^TM enables trimming the optical into digital format after packaging. It allows trimming to include other system variations.

CM3605’s adoption of Filtron™ technology allows the closest ambient light spectral sensitivity to real human eye responses. CM3605 has excellent temperature compensation capability for keeping the output stable under various temperature configurations. The robust refresh rate setting does not need an external RC low pass filter. Shutdown mode is available as a power saving requirement. The CM3605 operation voltage ranges from 2.6 V to 3.6 V and can detect a wide range of ambient light power environments. The maximum detecting light strength is 650 Lux.
