SI1132-A10-GMR

环境光传感器 I2C UV Index and Ambient Light Sensor

UV INDEX AND AMBIENT LIGHT SENSOR IC WITH I2C INTERFACE

Description SI1132-A10-GMR

The Si1132 is a low-power, ultraviolet (UV) index, and ambient light  sensor with I2C digital interface and programmable-event interrupt output.  This sensor IC includes an analog-to-digital converter, integrated highsensitivity  visible and infrared photodiodes, and digital signal processor.  The Si1132 offers excellent performance under a wide dynamic range  and a variety of light sources including direct sunlight. The Si1132 can  also work under dark glass covers. The photodiode response and  associated digital conversion circuitry provide excellent immunity to  artificial light flicker noise and natural light flutter noise. The Si1132  devices are provided in a 10-lead 2x2 mm QFN package and are capable  of operation from 1.71 to 3.6 V over the –40 to +85 °C temperature range.
