VCNL4040 product information

Fully Integrated Proximity and Ambient Light Sensor with Infrared Emitter, IC Interface, and Interrupt Function



VCNL4040 integrates a proximity sensor (PS), ambient   light sensor (ALS), and a high power IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. The...
The proximity sensor features an intelligent cancellation scheme, so that cross talk phenomenon is eliminated effectively. To accelerate the PS response time, smart persistence prevents the misjudgment of proximity sensing but also keeps a fast...
The patented FiltronTM technology achieves ambient light spectral sensitivity closest to real human eye response and offers the best background light cancellation capability (including sunlight) without utilizing the microcontrollers’ resources....
