VCNL4040M3OE

The VCNL4040M3OE is an integrated Proximity Sensor (PS), Ambient Light Sensor (ALS) and a high power IRED incorporates photodiodes, amplifiers and analog to digital converting circuits into a single chip by CMOS process. The 16-bit high resolution ALS offers excellent sensing capabilities with sufficient selections to fulfil most applications whether dark or high transparency lens design. High and low interrupt thresholds can be programmed for both ALS and PS, allowing the component to use a minimal amount of the microcontrollers resources. The proximity sensor features an intelligent cancellation scheme, so that cross talk phenomenon is eliminated effectively. The patented FiltronTM technology achieves ambient light spectral sensitivity closest to real human eye response and offers the best background light cancellation capability (including sunlight) without utilizing the microcontrollers resources.
