应用须知
- Controlling the ADS7805 With TMS320 Series DSPsPDF, 69 Kb, 档案已发布: Nov 9, 2004
The ADS7805 16-bit, bipolar input, parallel output analog-to-digital converter (ADC) has features that allow for an easy interface to many of the TMS320 series of digital signal processors from Texas Instruments. This application report focuses on configuring, sampling, and converting analog data presented to the ADS7805 ADC, with software examples using the TMS320C6713 and TMS320C5416 DSPs.

Upgrading to the new ADS85xx 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
