ams TSL25721 Ambient Light Sensor

Ă—

Description

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 TAOS’ patented dual-diode technology and the UV rejection filter incorporated in the package. The operating range can be extended to 60000 LUX when the low-gain mode is use. The TSL2572 device is particularly useful for enabling automatic brightness control (ABC) in large LCD flat-panel TVs and displays by providing optimum viewing in diverse lighting conditions (daytime versus nighttime viewing) while significantly reducing energy consumption to meet the stringent ENERGY STAR requirements.
