TSL25721FN is a compact dual-channel ambient light sensor for I²C-controlled display and lighting applications.

Best for

  • I²C ambient light measurement
  • Display backlight control
  • Compact optical sensor designs

Avoid if

  • A fixed 1.8 V I²C bus is required
  • Cover-glass spectral attenuation cannot be calibrated
  • A confirmed lifecycle status is required from supplied sources

Check before use

  • Set integration time and gain for the expected illuminance range.
  • Use the dual-channel lux equation and account for glass attenuation.
  • Provide pull-up resistors for SDA, SCL, and the open-drain INT output.
