        AH3144E  AH3144L  
                        、                是由电压调整器，霍尔电压发生器，                        ，差分放大器，史密特触发器和集电极开路的输出级组  
                                                                    ，，  
成的磁敏传感电路，其输入为磁感应强度，输出是一个数字电压讯号。它是一种单磁极工作的磁敏电路，适合于矩  
形或者柱形磁体下工作。AH3134L    的工作温度范围为-40~150℃，可应用于汽车工业和军事工程中。它们有2  种封  
装形式：TO-92UA  和TO-92T。
