ams OSRAM TSL2522 Highly Sensitive Ambient Light Sensor
ams OSRAM TSL2522 Highly Sensitive Ambient Light Sensor supplies two concurrent ambient light sensing channels, which can be arbitrarily connected to the photodiodes through a programmable multiplexer. The TSL2522 contains a set of Photopic photodiodes and a set of Infrared photodiodes. The architecture accurately measures ambient light and allows the calculation of the irradiance of different light sources. Calculation results improve display appearance and image taking.
The ams OSRAM TSL2522 features ambient light sensing and light flicker detection. The device is available in a 2.0mm x 1.0mm x 0.5mm low-profile, small OLGA package.
