A1381EUA-T傳感器變送器的磁性傳感器-線性羅盤（IC）規(guī)格書PDF中文資料

A1381EUA-T屬于傳感器變送器的磁性傳感器-線性羅盤（IC）。由Allegro MicroSystems制造生產(chǎn)的A1381EUA-T磁性傳感器 - 線性，羅盤（IC）該系列產(chǎn)品可用于將磁場強度作為一個可變數(shù)量進行測量，而相比之下，類似產(chǎn)品僅檢測是否存在強度超過某個限值的磁場。常見的應用包括測量地球磁場，以類似于傳統(tǒng)羅盤的方式進行定向，市面上的一些器件允許以相對于磁場的物理方向直接讀取測量值。

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.
