VCNL3020 Proximity Sensor with Infrared Emitter

Vishay Semiconductors VCNL3020 Fully Integrated Proximity Sensor with Infrared Emitter includes a built-in infrared LED and photo-pin-diode for proximity function. The 16-bit effective resolution for proximity detection range ensures excellent crosstalk immunity. The Vishay Semiconductors VCNL3020 Proximity Sensor with Infrared Emitter also features excellent ambient light suppression by signal modulation, an I²C bus interface, and digital output. The standard serial digital interface easily accesses the proximity signal without complex calculation and programming by an external controller. A flexible programmable interrupt pin is also available.
