ADA4805 output voltage swing

I am testing  current capability of op-amps by evaluating voltage swing to rails with simulation in PSpice.

I do it by sweeping through a current source at the output (at 75°). For negative rail (and currents) the V2 is set to 0V.

However ,ADA4805 shows weird behavour: it is supposed to be RRO, but the output is almost 1 V away from V+.

Have I missed something in the data sheet or perhaps there is a problem with the model?
