<br />下边的英文摘自《A Designer's Guide to Instrumentation Amplifiers》。<br /><br />阅读的过程中，进行简短地翻译下，提高自己的认识，中有翻译不当的地方，还请各位帮忙指出斧正，谢谢。<br /><br />Monolithic difference amplifiers are a special category of in-amps that are usually designed to be used in applications where large dc or ac common-mode voltages are present. This includes many general current sensing applications, such as motor control, battery chargers, and power converters. In addition, there are numerous high common-mode voltage automotive current sensing applications, including: battery cell voltage monitoring, transmission controls, fuel injection controls, engine management, suspension controls, electronic steering, electronic parking brake, and hybrid vehicle drive/hybrid battery control. Because these amplifiers are typically used to sense current by accurately amplifying the small differential voltage across a shunt resistor in the load path, they are often called current shunt amplifiers.<br /><br /><br />译文：<br /><br /> 差分放大器，属于一种特殊的仪表放大器，通常被设计用于需要较大的直流或交流共模干扰的场所。这其中包括通用的电流检测应用，如电机控制、电池充电和电源转换；另包括大量高共模电平的汽车电流检测应用，如电池电平监测、传动控制、燃油喷射控制、发动机管理、悬挂控制、电控转向、电控刹车、以及混合动力驱动和混合动力电池控制。因这此控制大多通过放大负载电路上分流电阻两端的电压差以获取电流，所以也常被称作电流分流放大器。 |
