模拟信号调理通常是指对模拟输入/输出信号进行电学处理,其性能好坏对电子系统指标起着举足轻重的作用。在模拟输入调理电路部分,主要介绍了单端输入电压/电流的调理电路、传感器信号的调理电路;在模拟输出调理电路部分,分别介绍了电压输出信号、电流输出信号和功率驱动信号的调理电路;最后给出了调理电路设计应注意的几个问题。
Analog signal conditioning usually refers to the analog input / output signals for electrical processing, its performance is good or bad for electronic system indicators play a decisive role. In the part of the analog input conditioning circuit, the single-ended input voltage / current conditioning circuit and the sensor signal conditioning circuit are introduced. In the part of the analog output conditioning circuit, the voltage output signal, the current output signal and the power drive signal conditioning circuit Finally, some problems that should be paid attention to in the design of conditioning circuit are given.
