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.

This publication represents the largest LTC commitmentto an application note to date. No other application noteabsorbed as much effort, took so long or cost so much.This level of activity is justified by our belief that high speedmonolithic amplifiers greatly interest users.

前面討論了很多內容，基本上涉及了有關PCB板的絕大部分相關的知識。第二章探討了傳輸線的基本原理，第三章探討了串擾，在第四章里我們闡述了許多在現代設計中必須關注的非理想互連的問題。對于信號從驅動端引腳到接收端引腳的電氣路徑的相關問題，我們已經做了一些探究，然而對于硅芯片，即處于封裝內部的IC來說，其信號傳輸通常要通過過孔和連接器來進行，對這樣的情況我們該如何處理？在本章中，我們將通過對封裝、過孔和連接器的研究，闡述其原理，從而指導大家在設計的時候對整個電氣路徑進行完整地分析，即從驅動端內部IC芯片的焊盤到接受器IC芯片的焊盤。
