A1315中文资料Linear Hall-Effect Sensor ICs with Analog Output数据手册Allegro规格书

描述 Description

The Allegro A1315 linear Hall-effect sensor ICs has been designed specifically to meet higher accuracy and smaller package requirements.

The accuracy of this device is enhanced via end-of-line optimization and features non-volatile memory to optimize device sensitivity and the quiescent voltage output for a given application or circuit.

The A1315 is an ideal solution for use in automotive and industrial applications requiring high accuracy, and operate across an extended temperature range, –40°C to 150°C.

The A1315 is offered in two package styles. The LH is a SOT-23W style, miniature, low profile package for surface-mount applications. The UA is a 3-pin, ultra-mini, single inline package (SIP) for through-hole mounting. Both packages are lead (Pb) free, with 100% matte tin leadframe plating.

特性 Features

• 3.3 V supply operation
• QVO temperature coefficient programmed at Allegro™ for improved accuracy
• High bandwidth, low noise analog output
• High speed chopping scheme minimizes QVO drift across operating temperature range
• Temperature-stable quiescent voltage output and sensitivity

简介

A1315属于传感器变送器的磁性传感器-线性罗盘（IC）。由Allegro制造生产的A1315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。
