  Power Supply Design for the ADS41xx (Rev. A)
  PDF, 401 Kb, Revision: A, File published: Dec 29, 2011
  System designers traditionally power the high-speed data converter in their systems from a low-noise, low-dropout linear regulator (LDO) in order to achieve the performance described in the analog-to-digital converter (ADC) data sheet. However, LDOs inherently are not very power efficient. Switching regulators, on the other hand, offer good power efficiency but typically come with higher output no

  Band-Pass Filter Design Techniques for High-Speed ADCs
  PDF, 733 Kb, File published: Feb 27, 2012
  Several well-known methods exist for designing passive inductor-capacitor (LC) filters with resistive load terminations. However, when LC filters are used to drive the analog input pins of a high-speed analog-to-digital converter (ADC), special consideration must be given to the ADC input impedance. Not accounting for the ADC input impedance often results in a filter design that does not meet the
