- Upgrading From ADS7808/09 to ADS8508/09 DevicesPDF, 66 Kb, 档案已发布: Jun 12, 2007
The information contained in this document applies to current applications using the ADS7808 or ADS7809 in a surface-mount SOIC (DW) package.This document is a guide to users of the ADS7808/09 devices with regards to potential compatibility issues when upgrading to the new ADS8508 and ADS8509 series of devices. - Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Kb, 修订版: A, 档案已发布: 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 - Determining Minimum Acquisition Times for SAR ADCs, part 2PDF, 215 Kb, 档案已发布: 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
