4-20mA，0-10V电流~电压模拟信号光电隔离放大器
iso u-p-o 系列直流电压信号隔离放大器是一种将电压信号转换成按比例输出的隔离电流或电压信号的混合集成电路。该ic内部含有一组高隔离的dc/dc电源和电压信号高效率耦合隔离变换电路等，可以将直流电压小信号进行隔离放大（u/u）输出或直接转换为直流电流（u /i）信号输出。较大的输入阻抗（≥1 mω）,较强的带负载能力（电流输出＞650ω,电压输出≥2k&o
便携式位置探测仪信号接收装置电路设计
<span id="LbZY">清管器在管道中运行时，其上的信号发射器发射出电磁脉冲信号，通过便携式位置探测仪上的信号接收装置接收信号，经过信号处理部分对信号进行解码、识别，最终将探测结果显示在液晶显示屏上。为了满足便携性的要求，探测仪采用低功耗设计，并大量使用贴片元件和功能集成的IC 。经过深入的理论研究和测试，制造出了试验样机，该样机圆满地完成了多种环境下的试验，并取得了良好的效果。<br /

High-Speed Digital System desi
前面讨论了很多内容，基本上涉及了有关PCB板的绝大部分相关的知识。第二章探讨了传输线的基本原理，第三章探讨了串扰，在第四章里我们阐述了许多在现代设计中必须关注的非理想互连的问题。对于信号从驱动端引脚到接收端引脚的电气路径的相关问题，我们已经做了一些探究，然而对于硅芯片，即处于封装内部的IC来说，其信号传输通常要通过过孔和连接器来进行，对这样的情况我们该如何处理？在本章中，我们将通过对封装、过孔和连
