  Design for a Wideband Differential Transimpedance DAC Output (Rev. A)
  PDF, 438 Kb, Revision: A, File published: Oct 17, 2016
  High-speed digital-to-analog converters commonly offer a complementary current output signal. Most output interface implementations use either a resistive load and/or a transformer to convert this current source signal to a voltage. Where a dc-coupled interface is required, a carefully designed differential transimpedance stage can offer an attractive alternative. Design considerations and options

  Wireline Data Transmission and Reception
  PDF, 191 Kb, File published: Jan 27, 2010
  Many types of wires are widely used to transmit data. Specifically, Category 3 and Category 5 (Cat3 and Cat5e, respectively)—also known as unshielded twisted pair or UTP lines—are now recommended for new telephone installations. Coaxial (coax) cables are used to distribute cable television (CATV) signals throughout a home. #12 and #14 American wire gauge (AWG) electric power distribution wire is a

  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

  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

  Tuning in Amplifiers
  PDF, 44 Kb, File published: Oct 2, 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 Kb, File published: Oct 2, 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.
