Vishay VCNL36821S IRED Integrated Proximity Sensor is fully integrated with an infrared emitter, a photodiode for proximity measurement, and a signal processing IC in a single package with a 12-bit ADC. With a range of up to 30cm (12″), this stand-alone component simplifies the use and design-in of proximity sensors as no mechanical barriers are required to optically isolate the emitter from the detector. The VCNL36821S is offered in a miniature, surface mount, 2.55mm x 2.05mm leadless package (LLP) with a low profile of 1mm. The device is designed to meet the low height requirements needed for use in smartphones, mobile phones, digital cameras, and tablet PC applications.
