Application Notes
- Thermal Noise Analysis in ECG ApplicationsPDF, 114 Kb, File published: May 3, 2011
This article discusses the thermal noise source of electrocardiogram (ECG) applications basedon the ADS1298 and ADS1298R family of multichannel, simultaneous sampling, 24-bit, delta-sigma (О”ОЈ) analog-to-digital converters (ADCs). This report offers several observations on identifying the major sources of thermal noise in an ECG system, and makes several recommendations regarding how to improve t - Improving Common-Mode Rejection Using the Right-Leg Drive AmplifierPDF, 297 Kb, File published: Jul 6, 2011
This article discusses the need to improve common-mode rejection (CMR) in electrocardiogram (ECG) subsystem applications. Several different techniques to improve CMR while also considering both patient and operator safety are presented. This report also reviews the implementation of the right-leg drive (RLD) loop technique to improve CMR using the ADS129x family of analog-to-digital converters (in - Analog Front-End Design for ECG Systems Using Delta-Sigma ADCs (Rev. A)PDF, 191 Kb, Revision: A, File published: 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, File published: 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.
