应用须知
- Using the ADS7869 Reference Design Evaluation ModulePDF, 205 Kb, 档案已发布: Oct 26, 2005
This application report describes the characteristics, operation, and use of the ADS7869 for the Motor Control Demo Board. This board is used as part of the demonstration materials for the Digital Motor Control Seminar presented by Texas Instruments. A complete circuit description and schematic diagram are included. - 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.
