  AB-174: Getting the Full Potential from your ADC (Rev. A)
  PDF, 72 Кб, Версия: A, Файл опубликован: 28 июн 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

  Assembly of a data-acquisition system with its many parts (multiplexed, amplifiers, ADC, voltage reference, etc.) can be complex and expensive. The new Burr-Brown ADS7870 solves the problem with its 12-bit low-power CMOS data acquisition system containing all parts mentioned, and extras. The space saving system is in a samll (SSOP-28 surface-mount) plastic package.

  Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
  PDF, 227 Кб, Версия: A, Файл опубликован: 10 ноя 2010
  This application report analyzes a simple method for calculating minimum acquisition times for successive-approximation register analog-to-digital converters (SAR ADCs). The input structure of the ADC is examined along with the driving circuit. The voltage on the sampling capacitor is then determined for the case when a step function is applied to the input of the driving circuit. Three different
