TSL2540

ALS, Light-to-Digital Sensor

The TSL2540 is a very-high sensitivity light-to-digital converter

that transforms light intensity into a digital signal output

capable of direct I²C interface. The ALS sensor features 2 output

channels, a visible channel and an IR channel. The visible

channel has a photodiode with a UV and IR blocking filter

whereas the IR channel has a photodiode with an IR pass filter.

Each channel has a dedicated data converter producing a 16-bit

output. This architecture allows applications to accurately

measure ambient light which enables devices to calculate

illuminance to control a display backlight.

Ordering Information and Content Guide appear at end of

datasheet.
