Notas de aplicación

  • Interfacing the ADS786x to the MSP430F2013
    PDF, 90 Kb, Archivo publicado: 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.
  • Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
    PDF, 227 Kb, Revisión: A, Archivo publicado: 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 2
    PDF, 215 Kb, Archivo publicado: marzo 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

    This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (О”ОЈ), successive approximation register (SAR), and pipeline analog-to-digital (A/D) converter specifications and performance characteristics. Although there is a considerable amount of detail in this document, the product data sheet for a particular product specification is the best and final reference.
