描述

The TSL2522 features ambient light sensing and light flicker detection. The device comes in a low-profile and small footprint, L2.0mm x W1.0mm x H0.5mm OLGA package. The Ambient Light Sensing function provides two concurrent ambient light sensing channels, which can be arbitrarily connected to the photodiodes via a programmable multiplexer. The device incorporates a set of Photopic photodiodes and a set of Infrared photodiodes.
