TMD2671数据手册传感器变送器的光学传感器-环境光IR红外线UV紫外线传感器规格书PDF

描述 Description

The TMD2671 family of devices provides a complete proximity detection system and digital interface logic in a single 8-pin package. The proximity detector includes a digital proximity sensor with integrated LED driver, and IR LED. The proximity function is calibrated to 100 mm (without cover glass), thus eliminating the need for end-equipment or sub-assembly factory calibration. The proximity detection feature operates from sunlight to dark rooms. The wide dynamic range also allows for operation in short distance detection behind dark glass such as with a cell phone. An internal state machine provides the ability to put the device into a low power mode providing very low average power consumption. The addition of the micro-optics lenses within the module provide highly efficient transmission and reception of infrared energy, which lowers overall power dissipation for the detection function. Not Recommended for New Designs! ams does not recommend using the FN PACKAGE VARIANTS of this product for new designs.
