Overview

Si115x Data Sheet Proximity/Ambient Light Sensor IC with I2C Interface The Si115x-AB00/AB09/AB9x is an ambient light sensor, proximity, and gesture detector with I2C digital interface and programmable-event interrupt output.

This touchless sensor IC includes dual 23-bit analog-to-digital converters, an integrated high-sensitivity array of visible and infrared photodiodes, a digital signal processor, and up to three integrated LED drivers with programmable drive levels.

The Si115x offers excellent performance under a wide dynamic range and a variety of light sources, including direct sunlight.

Key Features

  • Proximity detector.
  • From under 1 cm, to 50 cm without additional lensing.
  • From under 1 cm, to 200 cm with additional lensing (e. g. , 5 mm hemispherical lens as in our EVB).
  • Up to three independent LED drivers.
  • 30 current settings from 5.6 mA to 360 mA for each LED driver.
  • Operates in direct sunlight with optional on-die 940 nm passband filter.
  • On die 940 bandpass filter that rejects unwanted visible light and IR from daylight an.
