TSL2572

Light-to-Digital Converter

The TSL2572 device family provides ambient light sensing (ALS)

that approximates human eye response to light intensity under

a variety of lighting conditions and through a variety of

attenuation materials. Accurate ALS measurements are the

result of ams OSRAM patented dual-diode technology and the

UV rejection filter incorporated in the package. In addition, the

operating range is extended to 60,000 lux in sunlight when the

low-gain mode is used.

While useful for general purpose light sensing, the TSL2572

device is particularly useful for display management to provide

optimum viewing in diverse lighting conditions while

extending battery life. The TSL2572 device family is ideally

suited for use in mobile handsets, TVs, tablets, monitors, and

portable media players where the display backlight may

account for 50% to 70% of the system power consumption.
