摘要:

数控电位器是一种新型CMOS模拟、数字混合信号处理集成电路芯片,目前这一新器件具有强大的生命力和非常广泛的应用前景。数控电位器自问世以来,主要产品均由国外公司生产,在国内这一新器件还不为很多从事电子技术方面工作的人员所知。通过对数控电位器的长期研究,结合四个典型的应用案例,由浅入深、逐级深入地对数控电位器的应用技术作了通俗易懂的介绍,可为相关教学和科技人员了解和掌握这一新器件的应用方法提供很好的参考。文中所有应用实例皆为作者原创设计,并通过NI Multisim 13软件仿真和实际电路测试。

Abstract:

Digital control potentiometer is a new type of CMOS analog and digital mixed signal processing IC chip,at present,this new device has a strong vitality and a very wide range of applications. Since the appearance of digitally control potentiometer,the main products are produced by foreign companies. In China,this new device is not known to many people engaged in the work of electronic technology. An introduction to the application of numerical control potentiometer technology made easy to understand was given by long-term studied on the Digital Potentiometer, combined with the four typical application cases,progressively,step by step in depth. It can provide a good reference for teaching and technical personnel to understand and master application methods of the new device. All of the application examples are original design,and are tested by the Multisim NI 13 software simulation and actual circuit.

Key words: DCP(Digitally Control Potentiometer), keying, programmable, MCU(Microcontroller Unit)
