  A Spreadsheet for Calculating the Frequency Response of the ADS1250-54 (Rev. A)
  PDF, 461 Kb, Revision: A, File published: Sep 5, 2003
  The ADS1250, ADS1251, ADS1252, ADS1253 and ADS1254 family of high-resolution analog-to-digital converters (ADCs) share an advanced delta-sigma (О”ОЈ) topology. This application note reviews the frequency characteristics of these devices and shows how to use a companion Microsoft Excel? spreadsheet (sbaa103a.zip), available for download from the TI web site, to calculate the frequency res

  AB-174: Getting the Full Potential from your ADC (Rev. A)
  PDF, 72 Kb, Revision: A, File published: Jun 28, 2002
  Many of today?s high-resolution ADCs (Analog-to-Digital Converters) are operating from a single supply and use fully differential inputs. This can be a problem for single-ended signals that are bipolar relative to common. This article illustrates circuit configurations that preserve the full-scale input range by using modern features, such as Programmable Gain Amplifiers (PGAs) and internal voltag
