VCNL4100
Description
VCNL4100 integrates a high sensitivity long distance proximity sensor (PS), ambient light sensor (ALS), and 940 nm IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip using a CMOS process.
Key Features
- for the best utilization of resources and power saving on the microcontroller
- For the 8-bit proximity sensing function, VCNL4100 has a built-in intelligent cancellation scheme that eliminates background light issues
- The persistence feature prevents false judgment of proximity sensing due to ambient light noise
