[原创] ADI ADPD2140测量入射红外光角度光学传感器解决方案

ADI公司的ADPD2140是用于测量入射红外光角度的光学传感器,辐射敏感面积为 0.31 mm2,具有低结电容和低暗电流,可实现与ADPD1080光度学前端的最佳集成,亦可与同步红外光源(例如发光二极管 (LED))结合使用,探测用户手部运动以进行手势识别.工作温度−40℃至 +85℃,主要用在便携设备上的用户手势界面控制,物体位置跟踪,工业/自动化监控,角度感应,接近感应和物体距离测量(三角测量).本文介绍了ADPD2140主要特性,功能框图以及评估板EVAL-ADPD2140Z主要特性,电路图和PCB布局图.

The ADPD2140 is an optical sensor that measures the angle of incident infrared light. Light angles calculated from the ADPD2140 response are linear to ±5°within an angular field of view of ±35°.

The ADPD2140 has a radiant sensitive area of 0.31 mm2. The low junction capacitance and low dark current of the ADPD2140 allows optimal integration with the ADPD1080 photometric front end. The ADPD2140 can be used with a synchronous infrared light source such as a light emitting diode (LED) to detect user hand movements for gesture recognition. The ADPD2140 requires four photodiode channels. Therefore, use the ADPD1080BCPZ with the ADPD2140.

Packaged in a small,clear mold, 2 mm×3 mm, 8-lead LFCSP, the ADPD2140 is specified over the −40℃ to +85℃ operating temperature range.
