Error in LTspice with ADA4932

I have downloaded the ADA4932 model from the web. I am using the circuit as shown in the attachment.
I think it is available without being clamped, but when I run the simulation in LTspice, it is clamped as shown in the attachment.

I think this is because the ±5V operation specification (Vee +1.4 to Vss-1.4) is being applied.

Is it a bug in LTspice for this phenomenon?

BR,

Takahiro

    You are right. The ADA4932 model is matching the Min instead of the Typ.

    It is being adjusted to match the Typ for both 5V and 10V supply.

    The updated…
