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 :
u Each power supply lead has to be bypassed to ground with a 10nF ceramic capacitor very close
to the device and a 10µF capacitor.
u To provide low inductance and low resistance common return, use a ground plane or common point
return for power and signal.
u 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.
u Use small resistor values to decrease time constant with parasitic capacitance.
u Choose component sizes as small as possible (SMD).
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.
