Everlight Electronics Presents Ambient Light/Proximity Sensor Package for Mobile and Smart Phones

Optical proximity sensors with integrated IR transmitters often have cross-talk issues caused by IR stray light. In order to overcome this challenging problem, Everlight implemented a unique package design to keep this effect to a minimum. Moreover, the proximity sensor comes with a background noise cancellation algorithm to improve the performance under the influence of ambient IR light produced by lamps or sunlight.



Designed to reduce the power consumption of handheld devices like smart phones, mobile phones and PDAs, the APM-16D25-11-DF8's proximity sensor has a fast sensing time with a short ON time for the IR LED to keep the power consumption low without sacrificing on sensitivity.



The APM-16D25-11-DF8's ambient light sensor incorporates a special optical filtering for closest mimic with human eye spectral response. Everlight offers eight different available settings - four different integration times and two gain settings - to achieve the best matching resolution and

illumination ranges under different application conditions.
