摘要
在智能化传感器系统中广泛采用仪表放大器构成信号的放大处理电路。放大差分信号的仪表放大器在实际应用中 ,要考虑输入共模电压范围、增益的选择、滤波、共模频率、输入电流回路设计等问题 ,以及选择信号的输入方式。针对这些问题 ,本文进行了较为详尽的讨论。
Instrument amplifier are used widely to process and amplify signals in intelligent sensor system. Common mode voltage,the choise of gain,design of filter,input bias current,and input methods of signal are considered in the practical application of it. For the above problems,elaborated discussion is given in this paper.
