ADG779 SPICE model

when adding spice model in LTSPICE, i found that a positive voltage on IN pin connect S1 to D (S1 ON). The datasheet specify the oposite logic : a positive input connect S2 to D (S2 ON). What is the correct behaviour ?

  • Hi thomas456,

    Thanks for bringing this to our attention. I have made a quick check and your observation is correct.

    For clarification, the ADG779 datasheet provides the correct behavior of the device.

    With this, I have made changes to the existing spice model (Rev 1.0) and have raised a request to update the product page (for Rev 2.0 model). It should be available within the next few days.
