Fully-integrated high-performance proximity and ambient light sensors

Aimed at applications such as handheld devices, notebooks, tablet PCs, industrial and consumer devices, Vishay's VCNL4040 fully-integrated proximity and ambient light sensors are now stocked by Mouser. The VCNL4040 integrates a proximity sensor (PS), ambient light sensor (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 offers exceptional 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, says the company.
