ADA4805 Output Voltage Swing

Category: Datasheet/Specs
Product Number: ADA4805

Hello at all

i would like to know if there is an issue with the spice model of the ADA4805 or just something i do not understand correctly in the datasheet.

With condition given in the datasheet:

The Output should be able to have an output swing of:

But the Spice model shown here: (simple voltage follower, no load or other tricky things)

is showing a significant gap between input and output (beginning at about 2.5V).

Supply voltage is 3.6V so there is more than enough headroom i think.

Could you please check this behaviour of the model?

Is that just a model issue?

--> The ADA4805-02EP is foreseen as a key component of a new design (space application) and it is the only Opamp that fullfill all requirements.

Thank you for your support!
