There are many things to consider when designing printed circuit boards (PCBs) for high-speed op amps. Without proper caution, excessive ringing, oscillation, and other degraded ac performance can easily occur in high-speed circuits. As a rule, keep signal traces short and wide to provide low inductance and low impedance paths. Ground any unused board space to reduce stray signal pickup. Ground critical components at a common point to eliminate voltage drop. Sockets add capacitance to the board and can affect high-frequency performance. Soldering the amplifier directly into the PCB without using any socket is better.
