Application Notes
- Interfacing the ADS786x to TMS470 ProcessorsPDF, 59 Kb, File published: Jul 10, 2006
This application report presents methods of interfacing the ADS7866/67/68 12/10/8-bit SAR analog-to-digital converter to the serial peripheral interface (SPI) port of the TMS470 processors. The flexible clocking scheme of the TMS470 SPI port, along with its internal 16-bit shift register provides an easy hardware/software interface to this series of high-speed, micro power SAR converters. - Interfacing the ADS786x to the MSP430F2013PDF, 90 Kb, File published: Jun 15, 2006
This application report presents methods of interfacing the ADS7866/67/68 12/10/8-bit SAR analog-to-digital converter to the MSP430F2013 universal serial interface (USI) in SPI mode. The flexible clocking scheme of the USI port, along with the internal 16-bit shift register, provides an easy hardware/software interface to this series of high-speed, micro-power SAR converters. - Using a SAR A/D Converter for Current Measurement in Motor Control Applications (Rev.

- Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Kb, Revision: A, File published: 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, File published: 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.
