Product Description
Product Overview
The TSL2572 device family is a light-to-digital converter offering ambient light sensing (ALS) that approximates human eye response. It features ams OSRAM's patented dual-diode technology and a UV rejection filter for accurate measurements under various lighting conditions and attenuation materials. The device extends its operating range to 60,000 lux in sunlight with low-gain mode. It is particularly useful for display management in mobile handsets, TVs, tablets, monitors, and portable media players, optimizing viewing and extending battery life by managing display backlight power consumption.
