Ambient light sensors

Fully integrated precision light measurement across a wide spectrum of wavelengths

Enable precise light measurements for cost-optimized systems using our ambient light sensors.  Our fully-integrated ambient light sensors use a photodiode sensor AFE to imitate a human eye response in a wide range of environmental light conditions enabling easier-to-use and more precise solutions than discrete optical sensors.
