A1308-9:采用小型超薄表面安装封装且带模拟输出的线性霍尔效应传感器 IC

Description

线性输出霍尔效应传感器的新应用(如位移和角位等)要求更高的精确度和更小的封装尺寸。Allegro A1308 和 A1309 线性霍尔效应传感器经过特别设计,满足这两个要求。这些温度稳定期间提供表面安装与通孔封装选择。

通过线端优化提高每个器件的精度。每个器件均配有非易失性内存,用于优化给定应用或电路的灵敏度和静态电压输出(QVO:磁场消失时输出)在 Allegro 线端测试中对温度系数进行编程,以实现高灵敏度和 QVO,A1308 和 A1309 还可在整个工作温度范围内实现最佳性能。

这些成比例霍尔效应传感器 IC 提供与所施加的磁场成比例的电压输出。该静态电压输出。静态电压输出可调节大约 50% 的电源电压。

凭借其各项特色功能,这些线性器件非常适合要求高准确度的汽车和工业应用,并能在 –40°C 到 150°C 的温度范围内正常工作。

各 BiCMOS 单片电路均整合可降低霍尔元件固有灵敏度漂移的霍尔元件温度补充电路、小信号高增益放大器、箝位低阻抗输出级和专有动态偏移消除技术。

A1308 和 A1309 提供两种封装形式选择。LH 是 SOT-23W 微型扁平封装,适合表面安装应用。UA 是超小型 3 引脚单列封装 (SIP),适合通孔安装。这两种封装都是无铅 (Pb) 封装,引脚框采用 100% 雾锡电镀。
