System Level Protection for High-voltage Multiplexers in Muti-channel Data Acquisition Systems

Discusses over-voltage and fault protection for data acquisition systems.
  • In the first module, The architecture of a multi-channel data acquisition system and how a multiplexer can be used to facilitate the implementation. Possible causes of fault condition in a typical data acquisition system are discussed, and how the fault condition can severely impact the normal operation of the system is explained.
  • In the second module, protection schemes that can be implemented to protect the system in fault condition using discrete components are discussed. Detailed data will be analyzed and scope captures will be shown to explain the pros and cons of each protection scheme.
  • In the third module, a couple multiplexer solution offered by Texas Instruments that have integrated fault protection is discussed. The features of these multiplexers will be discussed in detail to illustrate how they make the system more robust.
  • In the fourth section, comparison will be made among the different protection schemes and recommendations will be discussed to address the fault protection need in the data acquisition system.
