  RLC Filter Design for ADC Interface Applications (Rev. A)
  PDF, 299 Кб, Версия: A, Файл опубликован: 13 май 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 Кб, Файл опубликован: 22 апр 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

  Measuring Board Parasitics in High-Speed Analog Design
  PDF, 134 Кб, Файл опубликован: 7 июл 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 Кб, Версия: A, Файл опубликован: 17 янв 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

  Tuning in Amplifiers
  PDF, 44 Кб, Файл опубликован: 2 окт 2000
  Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket?

  Single-Supply Operation of Operational Amplifiers
  PDF, 77 Кб, Файл опубликован: 2 окт 2000
  Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.

  Op Amp Performance Analysis
  PDF, 76 Кб, Файл опубликован: 2 окт 2000
  This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
