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 - A Glossary of Analog-to-Digital Specifications and Performance Characteristics (Rev. B)PDF, 425 Kb, Revision: B, File published: Oct 9, 2011
This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (О”ОЈ), successive approximation register (SAR), and pipeline analog-to-digital (A/D) converter specifications and performance characteristics. Although there is a considerable amount of detail in this document, the product data sheet for a particular product specification is the best and final reference. - Interfacing the ADS7870 and the MC68HC11E9 Analog to Microcomputer Made EasyPDF, 82 Kb, File published: 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. - Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Kb, Revision: A, File published: 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.
