VCNL4040 - Fully Integrated Proximity and Ambient Light Sensor

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.

• 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 response time. In active force mode, a single measurement can be requested, allowing another good approach for more design flexibility to fulfill different kinds of.
