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

簡介

A1315屬于傳感器變送器的磁性傳感器-線性羅盤（IC）。由制造生產(chǎn)的A1315磁性傳感器 - 線性，羅盤（IC）該系列產(chǎn)品可用于將磁場強(qiáng)度作為一個可變數(shù)量進(jìn)行測量，而相比之下，類似產(chǎn)品僅檢測是否存在強(qiáng)度超過某個限值的磁場。常見的應(yīng)用包括測量地球磁場，以類似于傳統(tǒng)羅盤的方式進(jìn)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。
