Notas de aplicación
- RLC Filter Design for ADC Interface Applications (Rev. A)PDF, 299 Kb, Revisión: A, Archivo publicado: mayo 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 DriversPDF, 273 Kb, Archivo publicado: abr 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 DesignPDF, 134 Kb, Archivo publicado: 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
