TSL2520

Highly Sensitive Ambient Light Sensor

The TSL2520 features ambient light sensing and 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.

TSL2520 incorporates a set of Infrared photodiodes and a set of

Clear photodiodes. The Clear photodiode area is covered with

a UV/IR blocking filter.

This architecture accurately measures ambient light and

enables the calculation of irradiance of different light sources.

Calculation results help to improve display appearance and

picture taking.

Ordering Information and Content Guide appear at end of
