The SY22309AS22-J01 device, an ambient light sensor (ALS) with clear channel, features high sensitivity, wide dynamic range and fast communication speed through I²C interface.
The SY22309AS22-J01 has 2 photodiode arrays. ALS PD is to sense visible light which includes 6 sensitive ranges and Clear PD is to sense visible and infrared which includes 2 sensitive ranges. ALS channel reading (digital count) is proportional to the illuminance regardless of the light sources while Clear channel reading is related to light source due to its full spectrum response; furthermore, no extra data manipulation is required. It also has a built-in circuit to reject the 50Hz/60Hz flicker noise caused by indoor light sources. Due to a well-engineered optical coating on the top of the ALS PD, its spectral response is almost the same as human eye’s photopic vision. Thus, system can tell the external light source type by checking the ratio of Clear/ALS channel data, then different preset correction coefficient can be chosen to adapt to different light sources.
The SY22309AS22-J01 is available in a small SMD L2.0mm×W1.5mm×H0.6mm package.
