  Interfacing the TLV1544/1548 Analog Digital Converter to Digital Processors
  PDF, 266 Kb, 档案已发布: Aug 1, 1997
  This Application Report describes the hardware and software requirements for interfacing an A/D converter to a DSP and to a MCU. The 10-bit A/D converter TLV1544 (4 analog input channels) and the TLV1548 (8 analog input channels) from Texas Instruments have been used to develop such interface. Example software code has been written showing how to program the DSP and the MCU to control the A/D conv

  Choosing an ADC and Op Amp for Minimum Offset
  PDF, 72 Kb, 档案已发布: Oct 28, 1999
  Designing a mixed-signal circuit containing analog and digital components can be a challenge to the development engineer. Requirements such as a low single-polarity supply voltage and a high degree of precision may conflict, and make the choice of components and the best circuit design difficult. This report discusses problems that arise in using operational amplifiers (op amps) for signal conditi

  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 2
  PDF, 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
