AMS AG TCS3701 product image

The TCS3701 is a very-high sensitivity light-to-digital converter that features ambient light and color (RGB) sensing in parallel with IR proximity detection. The Ambient light and color sensing function provides five concurrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband.

Key features

  • Ultra-high ALS and color sensitivity
  • 1024 X dynamic range by gain adjustment only
  • High proximity crosstalk compensation
  • On-chip self-calibration of ALS and proximity functions


Additional features:

Other Features

  • 0.18 µm process technology with 1.8 V I²C
  • Companion non-predictive asynchronous algorithm


  • Enables maximum design flexibility for operation behind Organic LED displays or dark inked glass
  • Enables dark room to sunlight operation
  • Reduces power consumption
  • When combined with a VCSEL emitter enables operation behind OLED
  • Enables ambient light measurement during display blanking periods



  • Display Backlight Control
  • Display Management
  • Ambient Light Sensing
  • Color Temperature Sensing
