MT3211

MT3211 is a highly sensitive wide dynamic range digital ambient light sensor (ALS) with a low-profile and small footprint. 

It includes Photopic, Clear and Flicker photodiodes (PDs), which provide ambient light and flicker frequency information of the ambient light source. 

MT3211 architecture accurately measures the ambient light, provides ultra-high sensitivity for luminance detection and very useful for smart lighting management, especially in robust backlight brightness, display appearance, camera flicker control.
