A1382LLHLT-T传感器变送器的磁性传感器-线性罗盘（IC）规格书PDF中文资料

A1382LLHLT-T属于传感器变送器的磁性传感器-线性罗盘（IC）。由Allegro MicroSystems制造生产的A1382LLHLT-T磁性传感器 - 线性，罗盘（IC）该系列产品可用于将磁场强度作为一个可变数量进行测量，而相比之下，类似产品仅检测是否存在强度超过某个限值的磁场。常见的应用包括测量地球磁场，以类似于传统罗盘的方式进行定向，市面上的一些器件允许以相对于磁场的物理方向直接读取测量值。

Description

New applications for linear output Hall effect sensors, such as displacement, angular position, and current measurement, require high accuracy in conjunction with small package size. The Allegro® A138x family of programmable linear Halleffect sensors was designed specifically to achieve both goals. These temperature-stable devices are available in a miniature surface mount package (SOT23-W) and an ultramini through hole single-in-line package. The accuracy of these devices is enhanced via programmability on the output pin for end-of-line optimization without the added complexity and cost of a fully programmable device.
