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 :
INPUT OFFSET VOLTAGE DRIFT VERSUS
TEMPERATURE
Each power supply lead has to be
by-passed to ground with a 10nF ceramic
capacitor very close to the device and
10 F capacitor.
To provide low inductance and low resist-
ance common return, use a ground plane
or common point return for power and sig-
nal.
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.
Use small resistor values to decrease time
constant with parasitic capacitance.
Choose component sizes as small as pos-
sible (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.
