A31010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

A31010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A31010磁性傳感器 - 線性，羅盤（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，類似產(chǎn)品僅檢測(cè)是否存在強(qiáng)度超過某個(gè)限值的磁場(chǎng)。常見的應(yīng)用包括測(cè)量地球磁場(chǎng)，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(duì)于磁場(chǎng)的物理方向直接讀取測(cè)量值。

FEATURES AND BENEFITS

? User-controlled sleep mode with fast (< 60 μs) wakeup

time for lag-free power savings

? 3.2 mA active and 25 μA sleep current reduces total

power consumption and extends battery life

? Operates down to 2.5 V supply for battery applications

? Low quiescent voltage output (QVO) maximizes output

range and resolution at ADC input

? Ambient temperature range from –20°C to 85°C suited

for personal electronics and gaming applications

DESCRIPTION

The A31010 family of linear Hall-effect sensor ICs provides a

voltage output that is proportional to the applied magnetic field.

The user-controlled sleep pin and rapid wakeup time allows

the A31010 to consume minimal power and provide magnetic

data quickly after waking up. These features coupled with a

low supply voltage rating of 2.5 V and non-ratiometric output

make this IC ideal for battery-powered applications.

Many human machine interface (HMI) applications such as

gaming controller joysticks, triggers, and keyboards will benefit

from the sensor’s unidirectional output.

These devices are available in a small 2 mm×3 mm, 0.75 mm

nominal height micro-leaded package (MLP/DFN). It is lead

(Pb) free with 100% matte tin leadframe plating

APPLICATIONS

? Game controllers

? Joysticks

? Triggers

? Personal electronics

? Keyboards

? Virtual and augmented

reality devices

? Human-machine interfaces
