Application Notes

  • Making the Most of a Low-Power, High-Speed Operational Amplifier
    PDF, 221 Kb, File published: Nov 22, 2009
    High-speed, high-performance operational amplifiers tend to be associated with high power dissipation. This application note compares the relative performance of several low-power, high-speed operational amplifiers and describes trade-offs to balance performance with low quiescent power dissipation.
  • A Numerical Solution to an Analog Problem
    PDF, 210 Kb, File published: Apr 25, 2010
    In order to derive a solution for an analog circuit problem, it is often useful to develop a model. This approach is generally accepted as developing an analytical model. However, finding the analytical solution is not always practical or possible as a result of higher-degree polynomials that require further resolution, or because of the time needed to develop the solution completely. In these sit
  • Current Feedback Amplifiers: Review, Stability Analysis, and Applications
    PDF, 53 Kb, File published: Nov 20, 2000
    The majority of op amp circuits are closed-loop feedback systems that implement classical control theory analysis. Analog designers are comfortable with Voltage FeedBack (VFB) op amps in a closed-loop system and are familiar with the ideal op amp approximations feedback permit. This application bulletin will demonstrate how CFB op amps can be analyzed in a similar fashion. Once the closed-loop sim
  • Stabilizing Current-Feedback Op Amps While Optimizing Circuit Performance
    PDF, 280 Kb, File published: Apr 28, 2004
    Optimizing a circuit design with a current-feedback (CFB) op amp is a relatively straightforward task, once one understands how CFB op amps achieve stability. This application note explains a 2nd-order CFB model so that any designer can better understand the flexibility of the CFB op amp. This report also discusses stability analysis, the effects of parasitic components due to PCBs, optimization

  • RLC Filter Design for ADC Interface Applications (Rev. A)
    PDF, 299 Kb, Revision: A, File published: May 13, 2015
    As high performance Analog-to-Digital Converters (ADCs) continue to improve in their performance, the last stage interface from the final amplifier into the converter inputs becomes a critical element in the system design if the full converter dynamic range is desired. This application note describes the performance and design equations for a simple passive 2nd-order filter used successfully in AD
  • ADS5500, OPA695: PC Board Layout for Low Distortion High-Speed ADC Drivers
    PDF, 273 Kb, File published: Apr 22, 2004
    Once an analog-to-digital converter (ADC) and a driver/interface have been selected for a given application, the next step to achieving excellent performance is laying out the printed circuit board (PCB) that will support the application. This application report describes several techniques for optimizing a high-speed, 14-bit performance, differential driver PCB layout using a wideband operation
  • Wideband Complementary Current Output DAC Single-Ended Interface
    PDF, 597 Kb, File published: Jun 21, 2005
    High-speed digital-to-analog converters (DACs) most often use a transformer-coupled output stage. In applications where this configuration is not practical, a single op ampdifferential to single-ended stage has often been used. This application note steps through the exact design equations required to achieve gain matching from each output as well as a matched input impedance to each of the DA
  • Measuring Board Parasitics in High-Speed Analog Design
    PDF, 134 Kb, File published: Jul 7, 2003
    Successful circuit designs using high-speed amplifiers can depend upon understanding and identifying parasitic PCB components. Simulating a design while including PCB parasitics can protect against unpleasant production surprises. This application report discusses an easy method for measuring parasitic components in a prototype or final PC board design by using a standard oscilloscope and low freq
  • Noise Analysis for High Speed Op Amps (Rev. A)
    PDF, 256 Kb, Revision: A, File published: Jan 17, 2005
    As system bandwidths have increased an accurate estimate of the noise contribution for each element in the signal channel has become increasingly important. Many designers are not however particularly comfortable with the calculations required to predict the total noise for an op amp or in the conversions between the different descriptions of noise. Considerable inconsistency between manufactu
