With 5V supply, the LMH6657/6658 slew rate limit is larger than that might be necessary to make full allowable output swing excursions.

LMH6657, LMH6658 SNOSA35F – AUGUST 2002 – REVISED MARCH 2013 www.ti.com OUTPUT PHASE REVERSAL This is a problem with some operational amplifiers. This effect is caused by phase reversal in the input stage due to saturation of one or more of the transistors when the inputs exceed the normal expected range of voltages. Some applications, such as servo control loops among others, are sensitive to this kind of behavior and would need special safeguards to ensure proper functioning.
