Application Notes
- Interfacing the ADS8345 to TMS320C5416 DSPPDF, 1.5 Мб, Файл опубликован: 5 дек 2002
This application report presents a hardware and software solution to interfacing the ADS8345 16-bit, 8-channel, 100 kHz analog-to-digital converter to the C5000? fixed point 16-bit family of digital signal processors (DSP). While this application report primarily focuses on the 8-channel ADS8345 part, the same solution can be utilized for the 4-channel ADS7841/ADS8341/ADS8343 and 8-channel ADS834 - Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Кб, Версия: A, Файл опубликован: 10 ноя 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 Кб, Файл опубликован: 17 мар 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
