A1363：低噪声，高精度，可编程线性霍尔效应传感器IC，具有先进的温度补偿和高带宽（120 kHz）模拟输出

The Allegro A1363 programmable linear Hall-effect current sensor IC has been designed to achieve high accuracy and resolution without compromising bandwidth. The goal is achieved through new proprietary linearly interpolated temperature compensation technology that is programmed at the Allegro factory and provides sensitivity and offset that are virtually flat across the full operating temperature range. Temperature compensation is done in the digital domain with integrated EEPROM technology, without sacrificing the analog signal path 120 kHz bandwidth, making this device ideal for HEV inverter and DC-to-DC converter applications.

该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。客户可以通过对V的编程来配置灵敏度和静态（零场）输出电压_CC.和输出引脚，以优化最终应用程序的性能。静态输出电压是用户可调的，距离电源电压的50％左右_CC.，并且输出灵敏度可在0.6至14 mV / g的范围内调节。

传感器IC采用高度敏感的霍尔元件，具有BICMOS接口集成电路，采用低噪声小信号高增益放大器，钳位低阻抗输出级和专有的高带宽动态偏移消除技术。这些霍尔效应技术的进步共同努力，为全新120 kHz带宽提供行业领先的传感分辨率。破碎的接地线检测以及用户可选的输出电压夹具也内置于该设备中，可用于汽车应用的高可靠性。亚博尊贵会员
