• Input impedance of AD8220 with ADG1209

    In my previous design, AD8220 was chosen because of the requirement of the extremely high input impedance. However, I need to modify the circuit design by adding a demultiplexer to perform a 1 to 4 switch function and ADG1209 seems suitable for my design…

  • need for 4 to 1 mux for high speed signals

    Hi,

    I am looking for a 4:1 multiplexer for analog signals with >300 MHz bandwidth.

    ADG1209 has a Ron too high.

    Have you other solutions ?

  • Are these parts pin-pin compatible with existing parts?

    Are these parts pin-pin compatible with existing parts?

     

    Yes, the ADG5208F/ADG5209F are pin-for-pin compatible with the ADG5208/ADG5209
    and ADG1208/ADG1209. They are drop in replacements if overvoltage protection is
    required. However…
  • RE: ADG1609 turn on behaviour

    Hi HillerT,

    As Eleuthere mentioned, the spike you measured on the switch pin when turning the power on/off is caused by parasitic capacitances between the switch pins and the supply rails.

    Considering just the IC itself, there are three main categories…

  • FAQ: ADG52xxF

    Q1. What are the key benefits of these fault protected switches?

    A1.  There are a number of key features on these parts

    • Overvoltage fault protection to +/-55V levels in powered and unpowered state
    • Secondary supply rails to allow for user defined…
