正确的工具和规则使选择更容易。不久前,选择运算放大器还是一个相对直截了当的过程,每个供应商的产品都是在+/-15V下操作,而且大多数应用都可被划分为高速或高精确度应用。工程师们在为他们的设计选择可接受的运算放大器时只需要考虑几个参数。但是随著手持和便携式计算机、蜂窝通信、先进的汽车电子产品等等的出现,导致了事实上数以千计的运算放大器产品的开发。现在,制造商之间对大批量应用
The right tools and rules make the selection easier. Not so long ago, opting for an op amp was still a relatively straightforward process with each vendor’s product operating at +/- 15V, and most applications could be classified as high-speed or high-accuracy applications. Engineers only need to consider a few parameters when choosing an acceptable operational amplifier for their design. However, with the advent of handheld and portable computers, cellular communications, advanced automotive electronics, and the like, the de facto thousands of op amp products have been developed. Now, between manufacturers for high-volume applications
