CXHA3122霍尔效应传感器精确地跟踪磁通密度的微小变化，这种变化通常太小，无法操作霍尔效应开关。
作为运动检测器、齿轮传感器和接近检测器，它们是机械事件的磁驱动反射镜。作为电磁铁的敏感监测仪，它们可以有效地测量系统的性能，而系统负载可以忽略不计，同时提供与污染和电噪声环境的隔离。
每个霍尔效应集成电路包括霍尔传感元件、线性放大器和发射极跟随器输出级。通过在单个芯片上安装霍尔单元和放大器，可以将处理微小模拟信号的相关问题降到最低。

一.产品概述
The CXHA3122 Hall-effect sensors accurately track extremely small changes in magnetic flux density-changes generally too small to operate Hall-effect switches.
As motion detectors, gear tooth sensors, and proximity detectors, they are magnetically driven mirrors of mechanical events. As sensitive monitors of electromagnets, they can effectively measure a system’s performance with negligible system loading while providing isolation from contaminated and electrically noisy environments.
Each Hall-effect integrated circuit includes a Hall sensing element, linear amplifier, and emitter-follower output stage. Problems associated with handling tiny analog signals are minimized by having the Hall cell and amplifier on a single chip.
