Digital Filter Types in Delta-Sigma ADCs
PDF, 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

Calibration Routines and Register Value Generation for the ADS121x Series
PDF, 298 Kb, 档案已发布: Jun 19, 2003
In order to achieve the best possible performance, offset and gain can be often be calibrated in high-resolution analog-to-digital converters (ADCs). Changes in temperature, PGA gain, power supply voltage, or most importantly, decimation ratio can influence the accuracy of measurement. This application note explains how the calibration routines work and how to generate values for the full-scale re
