TSL27723 Ambient Light Sensor

Light-to-digital converter with proximity sensing, I2C Vbus = 1.8V interface

 

The TSL2772 device family provides both ambient light sensing (ALS) and, when coupled with an external IR LED, proximity detection. The device family is based on the TAOS patented dual-diode technology that enables accurate ALS results and approximates human eye response to light intensity under a variety of lighting conditions.

Key Features

  • Patented dual-diode architecture
  • 8M:1 dynamic range 
  • UV-rejection package
  • Proximity offset adjustment 
  • Proximity saturation indicator bit

Key Benefits

  • Enables operation in IR light environments
  • Enables operation in 60K lux sunlight and accurate sensing behind spectrally distorting materials
  • Improves lux accuracy across varying light sources
  • Compensates for internal system offset or IR LED crosstalk
  • Prevents false proximity detection in bright light
