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

by-passed to ground with a 10nF ceramic

capacitor very close to the device and

µF capacitor.

u To provide low inductance and low resist-

ance common return, use a ground plane

or common point return for power and sig-

nal.

u All leads must be wide and as short as pos-

sible 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 pos-

sible (SMD).

u 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.
