Description说明

The A132X family of linear Hall-effect sensor ICs are optimized, sensitive, and temperature-stable.该传感器芯片A132X系列线性霍尔效应进行了优化，灵敏度高，温度稳定。 These ratiometric Hall-effect sensor ICs provide a voltage output that is proportional to the applied magnetic field.这些成比例霍尔效应传感器IC提供的电压输出正比于外加磁场。 The A132X family has a quiescent output voltage that is 50% of the supply voltage and output sensitivity options of 2.5 mV/G, 3.125 mV/G, and 5 mV/G.该A132X系列具有静态输出电压为50 2.5％的电源电压和输出灵敏度选择毫伏/克，3.125毫伏/ G和5毫伏/克 The features of this family of devices are ideal for use in the harsh environments found in automotive and industrial linear and rotary position sensing systems.家庭设备的特点非常适合本系统使用的旋转位置感测和在恶劣的环境中发现在汽车和工业线性。

Each device has a BiCMOS monolithic circuit which integrates a Hall element, improved temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the Hall element, a small-signal high-gain amplifier, and a rail-to-rail low-impedance output stage.每个器件都具有BiCMOS单片电路，该电路集成了霍尔元件，改进的温度补偿电路，以降低增益放大器固有的灵敏度漂移的霍尔元件，小型信号高，轨对轨低阻抗输出级。

A proprietary dynamic offset cancellation technique, with an internal high-frequency clock, reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress.独有的动态偏移取消技术的时钟，内置一个高频率，减少了残余应力引起的失调电压通常由器件超模压，温度依存性及热。 The high frequency clock allows for a greater sampling rate, which results in higher accuracy and faster signal processing capability. This technique produces devices that have an extremely stable quiescent output voltage, are immune to mechanical stress, and have precise recoverability after temperature cycling.高频时钟可支持更高的采样率，从而导致更高的能力，精度和更快的信号处理。这项技术生产出的器件具有极端稳定的静态输出电压，可抗机械应力，并且精确的温度循环后可恢复。 Having the Hall element and an amplifier on a single chip minimizes many problems normally associated with low-level analog signals.将霍尔元件和放大器的单芯片上的模拟信号减少许多层面的问题通常与低。

Output precision is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.输出精度得到了内部增益和制造过程偏移修正调整，是在结束行中。
