VCNL Proximity & Ambient Light Sensors

Vishay Semiconductors VCNL Proximity and Ambient Light Sensors are optical sensors, each combining an IR emitter, PIN photodiode, ambient light detector, signal processing IC, with 16-bit resolution, and an I²C interface. These features are integrated to greatly simplify window and sensor placement, PCB layout, and communication functions in a wide variety of consumer and industrial applications. The combination of the proximity sensor, ambient light sensor, and infrared emitter into a single component not only simplifies the design-in process by making a mechanical barrier unnecessary but also virtually eliminates optical cross-talk in smartphones.
