In this application note a few ideas were explored. First, some common fault conditions for Analog Input Modules were examined and how they can impose a risk to a system’s reliability. Then using the fault protection features offered by TI’s Fault Protected Switches and Multiplexers it was shown that these common fault conditions can be handled by a Fault Protected Switch or Multiplexer. Finally, the key care-abouts to when implementing a TI Fault Protected Switch or Multiplexer to optimize not only protection but system performance, cost, and solution size. Table 4-1 shows devices available now built with integrated fault protection features.
