• 产品概述

    MT3101 is an infrared light to digital converter with a built-in 940nm VCSEL diode and I²C interfaces. This device provides infrared sensing to allow proximity estimation featured with interrupt function.

    MT3101 incorporates a photodiode, timing controller and ADC. The spectral response of MT3101 is optimized for infrared light whose wavelength is 940nm. MT3101 employs a noise cancellation scheme to highly reject unwanted ambient noise. The proximity engine features a wide range offset adjustment to compensate for unwanted IR energy reflection at the sensor.

    MT3101 is designed to meet the Class 1 laser safety limits including single faults in compliance with IEC/ EN 60825-1: 2014 and IEC/ EN 60825-1: 2007.
