一、概述电压比较器是一种常用的信号处理电路,用来判断输入信号之间的相对大小,它可以将输入的模拟量按它的量值大小转换成相应的逻辑代码(即逻辑“0”或逻辑“1”),所以常常用作模拟电路和数字电路之间联系的接口,它的这种功能使它在工业自动化、仪器仪表和各种电子控制设备中获得了广泛的应用。 First, an overview Voltage comparator is a commonly used signal processing circuit used to determine the relative size of the input signal, which can be input analog by its magnitude into the corresponding logic code (ie, logic 0 “Or logic” 1 "), it is often used as an interface between analog circuits and digital circuits, and its utility has led to its widespread use in industrial automation, instrumentation, and various electronic control devices.
