A1321LUA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

A1321LUA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A1321LUA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

The A132X family of linear Hall-effect sensor ICs are optimized, sensitive, and temperature-stable. These ratiometric Hall-effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. The A132X family has a quiescent output voltage that is 50 of the supply voltage and output sensitivity options of 2.5 mV/G, 3.125 mV/G, and 5m V/G. The features of this family of devices are ideal for use in the harsh environments found in automotive and industrial linear and rotary position sensing systems.
