PRINTED CIRCUIT LAYOUT
As for any high frequency device, a few rules must be observed when designing the PCB to get the best
performances from this high speed op amp.
From the most to the least important points :
On output, decrease capacitor load so as to avoid circuit stability being degraded which may cause
oscillation. You can also add a serial resistor in order to minimise its influence.

LARGE SIGNAL FOLLOWER RESPONSE

Each power supply lead has to be bypassed to ground with a 10nF ceramic capacitor very close
to the device and a 10 F capacitor.
To provide low inductance and low resistance common return, use a ground plane or common point
return for power and signal.
All leads must be wide and as short as possible especially for op amp inputs. This is in order to
decrease parasitic capacitance and inductance.
Use small resistor values to decrease time constant with parasitic capacitance.
Choose component sizes as small as possible (SMD).
