描述
 
ISL29043是一个综合的环境和红外光到数字转换器,一个内置的红外LED和I 2 C接口(SMBus兼容)。该设备采用两个独立的ADC,同时测量环境光线和接近平行。灵活的中断计划旨在利用最小的微控制器。对于环境光线传感器(ALS)的数据转换,ADC的转换光电二极管电流在每个样品(100ms的光灵敏度范围可达2000勒克斯)。ADC的拒绝人工光源造成的的50HZ/60HZ闪烁噪声。对于接近传感器(感应)数据转换,内置驱动器将在内部红外LED和接近传感器的ADC转换到数字的反射红外线强度。此ADC拒绝环境红外噪声(如阳光),有一个540μs转化时间。ISL29043提供低功耗运行的ALS和接近正常运作一个典型的136μA电流(110μA传感器和内部电路,为LED ......28μA)与传感净100μS220毫安电流脉冲,重复每800毫秒(或下)。ISL29043采用硬件引脚和软件位指示中断事件发生。被定义为一套窗外是测量一个ALS中断。接近中断被定义为测量超过阈值限制。用户可能还需要双方ALS /感应中断发生一次,在激活中断引脚前行至16倍。ISL29043是设计工作在-40°C以上,从2.25V到3.63V至+85° C的环境温度范围。它被打包在一个清晰,无铅10引脚ODFN包。
