Vishay VCNL4040SB Proximity Ambient Light Sensor
The VCNL4040SB is a fully integrated proximity and ambient light sensor module featuring an infrared emitter, ambient light sensor, proximity sensor, and signal conditioning IC. It operates both ALS and proximity detection in a parallel structure and utilizes Filtron™ technology for robust background light cancellation. The sensor offers immunity to red glow (940nm IRED), with programmable IRED sink current, and includes intelligent cancellation to reduce crosstalk. Its smart persistence scheme minimizes proximity sensor response time, and it is immune to fluorescent light flicker. The spectrum closely matches human eye response. Features include a programmable interrupt function for ALS and proximity sensors with adjustable thresholds and persistence to prevent false triggers. Suitable for use in handheld devices, notebooks, tablets, consumer electronics, and industrial applications.
