自从30年前美国FSC公司生产出世界第一只运算放大器(下文简称运放或OP)μA702以来,运放在模拟电子世界有着极其广泛的运用,对信号进行放大、比较、调制、解调、有源滤波和多种模拟运算等等。世界上各大生产家的新产品品种与日俱增,按其应用可分为六大系列。 一、OP的主要参数 了解、认识、掌握OP“家族”成员,恰当选用它们,无疑对电子产品开发、电子设备的技术改造,电子电路的工程设计,电子产品的维护保养都是大有助益的。 弄清OP的电气特性,并能正确测试诸多参数是准确选择OP、正确使用OP的前提。下面扼要介绍OP的重要电气参数的概念和测试电路(图1)。
Since the American FSC Corporation produced the world’s first operational amplifier (hereinafter referred to as op amp or OP) μA702 30 years ago, the op amp has an extremely wide range of applications in the analog electronics world. The op amp amplifies, compares, modulates, demodulates, Active filter and many kinds of simulation operation and so on. The world’s major producers of new product varieties growing, according to their application can be divided into six series. First, the main parameters of the OP Understanding, understanding, mastering OP “family” members, the proper selection of them, no doubt for the development of electronic products, electronic equipment, technological transformation, electronic circuit design, electronic product maintenance are helpful of. Understand the electrical properties of OP, and can correctly test many parameters is the correct choice of OP, the premise of the proper use of OP. The following summary of the important electrical parameters of the OP concept and test circuit (Figure 1).
