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 10

µF 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.
