VCNL4030X01 incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process.

VCNL4030X01 integrates a PS, 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 16-bit high resolution ALS for excellent sensing capabilities with sufficient selections to fulfill applications whether dark or high transparency lens design. ALS and PS offer a programmable interrupt with individual high and low thresholds offers the power savings on the microcontroller and features an intelligent cancellation scheme – cross talk is eliminated effectively.
