    PDF, 82 Kb, Datei veröffentlicht: Sep 27, 2000
    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.

    PDF, 72 Kb, Revision: A, Datei veröffentlicht: 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
  • Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
    PDF, 227 Kb, Revision: A, Datei veröffentlicht: Nov 10, 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

    PDF, 215 Kb, Datei veröffentlicht: Mar 17, 2011
    The input structure circuit of a successive-approximation register analog-to-digital converter (SAR ADC) incombination with the driving circuit forms a transfer function that can be used to determine minimum acquisition times for different types of applied input signals. This application report, which builds on Determining Minimum Acquisition Times for SAR ADCs When a Step Function is Applied to
