High input impedance and a wide input range are twohighly desirable features in a precision analog-to-digitalconverter, and the LTC®2449 delta-sigma ADC has both.With just a few external components, the LTC2449 formsan exceptional measurement system with very high inputimpedance and an input range that extends 300mV beyondthe supply rails.

Digital-to-analog converters (DACs) are prevalent inindustrial control and automated test applications.General-purpose automated test equipment often requiresmany channels of precisely controlled voltagesthat span several voltage ranges. The LTC2704 is ahighly integrated 16-bit, 4-channel DAC for high-endapplications. It has a wide range of features designed toincrease performance and simplify design.

Recent advances in low voltage silicon germaniumand BiCMOS processes have allowed the design andproduction of very high speed amplifi ers. Because theprocesses are low voltage, most of the amplifi er designshave incorporated differential inputs and outputs to regainand maximize total output signal swing. Since many lowvoltageapplications are single-ended, the questions arise,“How can I use a differential I/O amplifi er in a single-endedapplication?” and “What are the implications of suchuse?” This Design Note addresses some of the practicalimplications and demonstrates specifi c single-endedapplications using the 3GHz gain-bandwidth LTC6406differential I/O amplifi er.

Many 8-bit and 16-bit microcontrollers feature 10-bitinternal ADCs. A few include 12-bit ADCs, but these oftenhave poor or nonexistent AC specifi cations, and certainlylack the performance to meet the needs of an increasingnumber of applications. The LTC®2366 and its slowerspeed versions offer a high performance alternative, asshown in the AC specifi cations in Table 1. Compare theseguaranteed specifi cations with the ADC built into yourcurrent microcontroller.

Linear Technology’s High Frequency Product lineupincludes a variety of RF I/Q modulators. The purpose ofthis application note is to illustrate the circuits requiredto interface these modulators with several popular D/Aconverters. Such circuits typically are required to maximizethe voltage transfer from the DAC to the baseband inputsof the modulator, as well as provide some reconstructionfi ltering.

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、过孔和连接器的研究,阐述其原理,从而指导大家在设计的时候对整个电气路径进行完整地分析,即从驱动端内部IC芯片的焊盘到接受器IC芯片的焊盘。
