模拟电子 16位高精度多输入隔离模拟前端(AFE)
Abstract: This document explains how the Cupertino (MAXREFDES5#) subsystem reference design meets the higher resolution, higher voltage,and isolation needs of industrial control and industrial automation applications. Hardware and firmware design files as well as FFTs andhistograms from lab measur ...
模拟电子 校准触摸屏系统研究
Abstract: Mechanical misalignment and scaling factors lead to a mismatch between the values coming from a touchscreen panel (as translated by a touch screen controller) and the display (typically an LCD) on which the touch screenpanel is mounted. This tutorial discusses how to calibrate the touch ...
电源技术 一种改进的简单的电缆仿真模型
Abstract: Nonideal cable dispersive effects can affect system performance. This application note discusses the twomain loss effects related to cables (skin-effect and dielectric losses), and presents a simple method of modeling thecable for use in standard SPICE simulators.
电源技术 如何设计一个高效率的DC-DC转换器
Abstract: The DS1875 features a pulse-width modulation (PWM) controller that can be used to control aDC-DC converter. The DC-DC converter can then be used to generate the high bias voltages necessaryfor avalanche photodiodes (APDs). This application note describes the operation of a boost converte ...
电源技术 电感开关稳压器提高输入电压
Abstract: Uses the MAX641 switching controller and an external discrete charge pump to step up the input voltage. This circuitcan service low loads and is efficient when the output is two, three, four times the input voltage. Adding the MAX627 MOSdriver can further increase the output current capa ...
传感与控制 微机电系统(MEMS)控制驱动讨论
Abstract: The number of uses for microelectromechanical systems (MEMS) is growing—they allow us todo jobs once considered impossible. This tutorial explains the applications for MEMS and the increasingneed to provide precision control and drivers for these devices. Design and manufacturing c ...
嵌入式综合 1-Wire总线主机
Abstract: Communication with 1-Wire slave devices requires a 1-Wire master. There are numerous ways to build a 1-Wire master (see reference design 4206, "Choosing the Right 1-Wire Master for Embedded Applications"). Thisdocument describes the DS1WM, a synthesizable 1-Wire master that can be implem ...
通讯/手机编程 if an application works with restricted low level system calls, it must obtain a Microsoft Mobile2Ma
if an application works with restricted low level system calls, it must obtain a Microsoft Mobile2Market privileged signature. To get a privileged signature, logo certification is now a requirement, not an option! This article shows how to abstract some of the most common issues a developer will enc ...
