[原创] ADI ADPD2140W光学传感器解决方案

摘要: ADI公司的ADPD2140W是能检测入射红外光角度的光学传感器,和红外LED一起能检测用户手的运动和手势.具有2轴光角度测量, 工作温度−40°C到+105°C,主要用在用户接口控制的手势控制,光角度检测和接近检测.本文介绍了ADPD2140W主要特性,功能框推, ADPD2140W和ADPD1080连接图,以及评估板EVAL-ADPD2140Z主要特性,电路图和PCB设计图.



 The ADPD2140W is an optical sensor that detects and measures the angle of incident infrared light within a wide field of view and can be used in conjunction with an infrared light emitting diode (LED) to detect user hand movements or gestures.

The ADPD2140W has an illuminated, radiant sensitive area of 0.363 mm2. The low diode capacitance and low dark current of the ADPD2140W allows optimal integration with the ADPD1080 photometric front end. The ADPD2140W requires four photodiode channels. Therefore it is recommended to use the ADPD1080BCPZ with the ADPD2140W.

Packaged in a small, clear mold, 2 mm × 3 mm, 8-lead LFCSP, the ADPD2140W is specified over the −40°C to +105°C operating temperature range.

ADPD2140W主要特性:

2-axis light angle measurement

Linear response to the angle of incident light

Integrated visible light blocking optical filter

No external lens required
