A1382LUA-T屬于傳感器變送器的磁性傳感器-線(xiàn)性羅盤(pán)（IC）。由Allegro MicroSystems制造生產(chǎn)的A1382LUA-T磁性傳感器 - 線(xiàn)性，羅盤(pán)（IC）該系列產(chǎn)品可用于將磁場(chǎng)強(qiáng)度作為一個(gè)可變數(shù)量進(jìn)行測(cè)量，而相比之下，類(lèi)似產(chǎn)品僅檢測(cè)是否存在強(qiáng)度超過(guò)某個(gè)限值的磁場(chǎng)。常見(jiàn)的應(yīng)用包括測(cè)量地球磁場(chǎng)，以類(lèi)似于傳統(tǒng)羅盤(pán)的方式進(jìn)行定向，市面上的一些器件允許以相對(duì)于磁場(chǎng)的物理方向直接讀取測(cè)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.
