This application report describes the SPI timeout function of the ADS1258, ADS1258-EP, and ADS1158.The goal of this application report is to describe the SPI timeout function and operation. - Analog Front-End Design for ECG Systems Using Delta-Sigma ADCs (Rev. A)PDF, 191 Kb, 修订版: A, 档案已发布: Apr 13, 2010
This document discusses the characteristics of electrocardiogram (ECG) signals and different front-endapproaches for ECG signal acquisition. The tradeoffs between different approaches and the effects on overall system design are discussed. The report also includes descriptions of potential implementations of the front-end architecture using the ADS1258 and ADS1278 and respective noise measuremen - Digital Filter Types in Delta-Sigma ADCsPDF, 219 Kb, 档案已发布: Jun 27, 2017
This application report discusses digital filters which are a ubiquitous feature in delta-sigma analog todigital converters (ADCs). Digital low-pass filters are essential to the functionality of a delta-sigma ADCwhich relies on oversampling and noise shaping to push quantization noise out of band. There arevariations between the types of digital filters used in delta-sigma ADCs that provide - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev.
