CM32183 Low Power, High Sensitivity I2C Ambient Light Sensor

  CM32183 is a 16-bit low power, high sensitivity CMOS ambient light sensor operated via a simple I2C command. The sensor offers an active interruption feature that is triggered outside of the threshold window settings eliminating loading on the host. Active average power consumption is around 200uW.

  CM32183 incorporates a photodiode, amplifiers and analog/digital circuits on a single chip. Capella’s patented Filtron™ technology, a wafer level optical filter, provides the best spectral sensitivity to match human eye responses. The sensor has excellent temperature compensation to maintain output stability under changing temperature and its refresh rate setting does not need an external RC low pass filter. There is a programmable shutdown mode which reduces current consumption to 0.5uA.  Operating voltage ranges from 1.7V to 3.6V.
