DATA SHEET AND USECASE

Key Features:

• Ambient Light Sensing (ALS): Utilizes dual photodiodes to approximate human eye response, offering high sensitivity with performance down to 0.01 lux. This allows operation behind darkened glass.

• Proximity Detection: Fully calibrated to detect objects up to 100 mm without the need for factory calibration. Operates effectively under various lighting conditions, from bright sunlight to dark rooms.

• Programmable Features: Includes a programmable interrupt function with upper and lower thresholds, adjustable gain settings, and a wait timer programmable from 2.7 ms to over 8 seconds.

  Low Power Consumption: Incorporates an internal state machine that enables low power mode between ALS and proximity measurements, reducing average power consumption. Sleep mode power is typically 2.2 µA.
• I²C Interface: Supports communication speeds up to 400 kHz (I²C fast-mode) and includes a dedicated interrupt pin for efficient system integration.
