Industry’s first automotive low light ambient light sensor focuses on AEC-Q100 Grade 2 applications

New Products |
Intersil Corporation has introduced an automotive qualified ambient light sensor that can measure incident light levels down to 0.01 lux with near human eye spectral response. The ISL76671 is the industry's first low light ambient light sensor (ALS) that operates within the automotive temperature range of -40 to 105 degrees C, guaranteeing reliable performance without external temperature compensation.

The sensor features internal temperature compensation, fast 30 millisecond response time and excellent infrared (IR) rejection. The ALS operates from a 1.8 V to 3.0 V supply with an ultra-low operating current of less than 4 uA, and its voltage output can be connected directly to an ADC without buffering.

Available in a small 2.1mm x 2.1mm package, the ISL76671 is an ideal solution for light detection behind darkened glass and plastic bezels in a wide range of light-based control applications. The ultra-low light sensitivity (0.01 lux) enables excellent nighttime performance. (As a reference, the illumination from the full moon is typically from 0.25 to 1 lux, depending on location.)

The ISL76671 is assembled in a tiny 2.1mm x 2.1mm OFDN package with prices starting at $0.85 in 1,000-piece units.
