A1301和A1302是连续时间，比率，线性霍尔效应传感器。它们被优化以准确地提供的电压输出正比于所施加的磁场。这些设备有一个静态输出电压为电源电压的50％。提供两种输出灵敏度选择：2.5毫伏/ G典型的A1301和1.3毫伏/ G典型的A1302。霍尔效应包括在每个器件集成电路包括霍尔传感元件，一个线性放大器，和一个CMOS类输出结构。集成霍尔传感元件和单个芯片上的放大器最小化的许多通常与低电压电平的模拟signals.High精度在输出电平相关联的问题是由内部增益和期间偏移修整在尾线制成调整发言：制造业process.These特点使得用于位置的A1301和A1302理想的传感系统，线性目标运动和旋转运动的目标。它们非常适合在扩展温度范围的工业应用，从-40°C至125°C.Two器件封装类型可供选择：LH，安装表面3针SOT23W类型，UA，一个3引脚超SIP的通孔安装。每个封装在一个铅（Pb）免费版本（后缀，-T）采用100％雾锡电镀引线框架。The A1301 and A1302 are continuous-time, ratiometric, linear Hall-effect sensors. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. These devices have a quiescent output voltage that is 50% of the supply voltage. Two output sensitivity options are provided: 2.5 mV/G typical for the A1301, and 1.3 mV/G typical for the A1302. The Hall-effect integrated circuit included in each device includes a Hall sensing element, a linear amplifier, and a CMOS Class A output structure. Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.High precision in output levels is obtained by internal gain and offset trim adjust-ments made at end-of-line during the manufacturing process.These features make the A1301 and A1302 ideal for use in position sensing systems, for both linear target motion and rotational target motion. They are well-suited for industrial applications over extended temperature ranges, from –40°C to 125°C.Two device package types are available: LH, a 3-pin SOT23W type for surface mount, and UA, a 3-pin ultramini SIP for through-hole mount. Each package is available in a lead (Pb) free version (suffix, –T) with 100% matte tin plated lead-frame.
