STANDBY POSITION
STANDBY MODE
To put the device in standby, just apply a logic
level on the standby MOS input. As ground is a vir-
tual level for the device, threshold voltage has
VCC
standby
+
+
been refered to VCC at VCC - 1.6V typ.
In standby mode, the output goes in high imped-
ance in 200ns. Be aware that all maximum rating
must still be followed in this mode. It leads to
swing limitation while using the device in signal
multiplexing configuration with followers, differen-
tial input voltage must not exceed ±5V limiting in-
put swing to 2.5Vpp.

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.
LARGE SIGNAL FOLLOWER RESPONSE
From the most to the least important points :
❑ Each power supply lead has to be
by-passed to ground with a 10nF ceramic
capacitor very close to the device and
10µF 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.
STATIC OPEN LOOP VOLTAGE GAIN
❑ 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.
