一、绪言: 近年来,各种IC已被广泛地应用于电子计测设备,应用于运算放大器及调节器的主要有DTL,TTL;FET有时被用于变换器。总起来看使用IC的计测设备可靠性高性能稳定这是因为使用的IC具有较长的寿命,也正因为这一点DTL与TTL已有相当市场。特别是TIL由于价格低廉而被受到广泛地重视。虽说使用IC的设备对环境条件的要求比较高,需要有良好的空调空间,这一点远远超过其它民用设备。但是随着各种计测设备的进一步IC化,亦即IC的应用范围进
First, the introduction: In recent years, various IC has been widely used in electronic measurement equipment, used in operational amplifiers and regulators mainly DTL, TTL; FET is sometimes used in the converter. Overall look at the measurement equipment using IC High reliability and stability This is because the use of IC has a longer life, it is precisely because of this DTL and TTL have considerable market. In particular, TIL is widely valued due to its low price. Although the use of IC equipment on the environmental conditions of the higher requirements, the need for good air-conditioned space, which is far more than other civilian equipment. However, with the further IC measurement of various devices, that is, the scope of application of IC
