VCNL4100 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 with a dark or high transparency lens design. VCNL4100 offers individual programmable high and low threshold interrupt features for the best utilization of resources and power savings on the microcontroller.
