VCNL4200-SB (VISHAY)

VCNL4200 integrates a high sensitivity long distance proximity sensor (PS), ambient light sensor (ALS), and 940nm IRED into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip using a CMOS process. The 16-bit high resolution ALS offers excellent sensing capabilities with sufficient selections to fulfill most applications whether a dark or high transparency lens design. For the 12-bit / 16bit proximity sensing function, VCNL4200 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.
