SI1120 Datasheet Proximity/ambient Light Sensor

Manufacturer: Silicon Laboratories

Overview: Si1120 PROXIMITY/AMBIENT LIGHT SENSOR WITH PWM OUTPUT.

General Description

The Si1120 is a low-power, reflectance-based proximity and ambient light sensor with advanced analog signal processing and analog PWM output.

It includes an integrated differential photodiode, signal processor, and LED driver.

Proximity sensing is based on the measurement of reflected light from an external, optically-isolated, strobed LED.

Key Features

  • Typically 50 cm meter proximity.
  • High EMI immunity without range with single pulse shielded packaging.
  • Seven precision optical.
  • Power supply: 2.2.
  • 3.7 V measurement modes:.
  • Operating temperature range:.
  • 3 proximity ranges.
  • 40 to +85 °C.
  • 3 dc ambient ranges.
  • Typical 10 µA current.
  • 1 calibration mode consumption.
  • Low-noise ambient cancelling.
  • Programmable 400/50 mA LED circuit allows maximum constant current dri.
