AD8561 output

Category: Software
Product Number: AD8561
Software Version: LTSPICE 17.1.15

The AD8561 model in LTSPICE 17.1.15 appears to have the output and the complementary output mapped the wrong way round. The outputs go high when they should go low and vice versa. Response to a triangle wave shown below, n001 is the output pin. I noticed this has been raised before ( https://ez.analog.com/design-tools-and-calculators/ltspice/f/q-a/566887/ltspice-ad8561-macromodel-symbol), just letting you guys know the problem is ongoing.

    Hi  ,

    The model for this part had already been updated on our library, you can update your model library on LTspice and see it there.

    Thank you for your patience on waiting for this.

    Best Regards.

  • Hi DRBB,

    I got an answer with our Apps Team, and this concern already has a ticket raised Slight smile

    For the meantime, while the issue is being addressed in the model, as per our apps team, you can use the LT1016 Model for comparison. This is discussed in page 7 of our datasheet.

    I hope this one helps.

    Best Regards,

    Earl
