Notas de aplicación

  • The DDC112/'s Test Mode
    PDF, 82 Kb, Archivo publicado: sept 27, 2000
    This application bulletin covers the DDC112's test mode. It elaborates on the explanation given in the data sheet and is written with the purpose of helping you use the test mode to its fullest capability. It does assume a basic understanding of the DDC112's operation. For a good introduction to the DDC112, see the DDC112's data sheet.
  • Creating a Bipolar Input Range for the DDC112
    PDF, 86 Kb, Archivo publicado: sept 27, 2000
    The following sections of this application note review the DDC112?s input range, describe how to make it bipolar, show how to experiment with bipolar ranges using the DDC112 Evaluation Fixture and finally how to derive the noise contribution that comes with making the range bipolar.
  • Using External Integration Capacitors on the DDC112
    PDF, 56 Kb, Archivo publicado: sept 27, 2000
    This application bulletin discusses issues that arise when using external integration capacitors on the DDC112. It expands on the explanation given in the data sheet and provides some new data to help you select and use the capacitors. It does assume a basic understanding of the DDC112's operation.
  • Understanding The DDC112/'S Continuous and Non-Continuous Modes
    PDF, 74 Kb, Archivo publicado: sept 27, 2000
    This application bulletin provides additional information on how the DDC112's continuous and non-continuous modes work and how to effectively operate the part in either mode. It is intended to supplement the information in the DDC112's data sheet and therefore skips some of the basic explanations of operation. For a good introduction to the DDC112, please refer to the data sheet.
  • Retrieving Data from the DDC112
    PDF, 80 Kb, Archivo publicado: sept 27, 2000
    This application bulletin explains how to retrieve data from the DDC112. It elaborates on the discussion given in the DDC112 data sheet and provides additional information to allow you more flexiblity during retrieval. It is assumed that you have a basic understanding of the DDC112's operation.
  • Multi-DDC112 DUT Board for the DDC112 Evaluation Fixture
    PDF, 161 Kb, Archivo publicado: sept 27, 2000
    The DDC112 is capable of being daisy chained for use in systems with a large number of channels. To help in designing such a system, this application note describes the design of a multi-DDC112 DUT board that can be used with the standard evaluation fixture DEM-DDC112U-C.
  • Programming Tricks for Higher Conversion Speeds Utilizing Delta Sigma Converters
    PDF, 105 Kb, Archivo publicado: sept 27, 2000
    Delta-Sigma Analog-to-Digital Converters are well known for their innate ability to resolve an analog input signal to very small LSB voltage ranges. The primarily applications for this type of product is in the Industrial Process Control market such as direct transducer interface for pressure, temperature, flow, weigh scales and force measurement systems.
