  RE: ISO1211: ISO1211 noise problem

  Hi Mehmet, ISO1211 does employ capacitive isolation but this doesn't mean input noise can pass through it. Between internal isolation cap and external terminal, there is a lot of circuit that accepts inputs, modulates input data and then transmits...

  RE: Read analog voltage isolated

  Hi Antonio, Did you mean to say that you only need to find out if the power supply voltage is above or below a particular voltage, like for the Binary Input Module? If yes then, using ISO1211 might be a good single-chip solution. If you needed to...

  RE: isolation for discrete input with levels - open or ground

  Hi Jayalakshmi, Please do share more details about your input signal to make an optimum choice. It sounded like you have a field digital input coming from a sensor that needs to be isolated and given to an MCU. Please confirm if this is the use-case...
