A1373EKB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

A1373EKB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A1373EKB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

The A1373 and A1374 high precision linear Hall effect sensors are sensitive, temperature stable, linear devices with externally programmable features. This device family incorporates a chopper-stabilized amplifier, voltage regulator, programming logic, and an output amplifier on a single IC. The patented dynamic offset cancellation used with a chopper-stabilization technique provides extremely low offset and minimal temperature drift. A high frequency clock is used for chopping, to ensure high frequency signal processing capability. The A1373 and A1374 are ideal for use in automotive and industrial linear position-sensing applications that require increased reliability and accuracy over conventional contacting-potentiometer solutions. Key applications include: throttle position sensors, pedal position sensors, and suspension height sensors.
