Description

The A1301 and A1302 are continuous-time, ratiometric, linear Hall-effect sensors. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. These devices have a quiescent output voltage that is 50 of the supply voltage. Two output sensitivity options are provided: 2.5 mV/G typical for the A1301, and 1.3 mV/G typical for the A1302.

Features and Benefits

▪ Low-noise output

▪ Fast power-on time

▪ Ratiometric rail-to-rail output

▪ 4.5 to 6.0 V operation

▪ Solid-state reliability

▪ Factory-programmed at end-of-line for optimum performance

▪ Robust ESD performance

A1302ELHLT属于传感器，变送器 > 磁性传感器 - 线性，罗盘（IC）。Allegro MicroSystems制造生产的A1302ELHLT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。
