摘要
本文介绍了以TDA8902J数字功放为例的PCB设计原则和技术规范,对电路设计中的抗干扰性给出了具体的方案和措施,分析了布线中的电磁干扰问题,并找到了有效的对策。电路设计工程师在电路设计之初运用这些原则和方法能很好地解决布线中出现的问题。
In this paper,the author introduces the principle and technical specification that PCBdesigns on TDA8902J digital power amplifier as an example,provides concrete scheme andmeasure to the anti-interference in the circuit design,analyses the layout in Electro MagneticInterference,and finds the effective countermeasure.PCB designer can use these principlesand criterions to reduce EMI in layout.
