e) Socketing a high-speed part like the OPA4872
is not recommended. The additional lead length and
pin-to-pin capacitance introduced by the socket can
create an extremely troublesome parasitic network
that can make it almost impossible to achieve a
smooth, stable frequency response. Best results are
obtained by soldering the OPA4872 onto the board.

The OPA4872 is built using a very high-speed
complementary bipolar process. The internal junction

series resistors should be added into the two inputs.
Keep these resistor values as low as possible
because high values degrade both noise performance
and frequency response.
