ADA4817-1ARDZ in a transimpedance amplifier phase shift

We use the ADA4817-1ARDZ in a transimpedance amplifier. The TIA bandwidth is modest (~100 kHz) but the transimpedance is high, about 10 MV/A. We see differences in the TIA phase shift which appear to depend on the lot number of the ADA4817. What might cause this dependence? Thanks!
